Super excited about this shootout. Some of your older videos lead me to us the vortec heads on my last build and I was very impressed by the power I got. Junkyard gold
Hey that's amazing, really glad to hear that! There seems to be some guys that are still skeptical and hating on the vortecs so maybe the flow date will change some minds? haha
If you pick up used vortec heads at the wrecking yard or a swap meet. Look for cracks on the head gasket mating surface between the bolt holes and water jackets. Recently I was looking for some cores to rebuild for my 4.3L V6,97 vortec. Basically they're the same as the V8 heads. I took the heads off 2 engines to find 2 good heads with no cracked water jackets and no cracked/ badly pitted valve seats area. Machinist still managed to find a crack that I missed. He was able to repair it by hogging out the valve seat area and pressing in a new seat. I bought a pair of rebuilt vortec heads on Ebay about 2-3 years ago. They both had crack repairs. They only lasted about 20k before I had to add stop leak to the radiator. I hate that stuff,clogged up my heater core. Luckily after I replaced my heads,I was able to back flush it with a hose and the heater works fine now. The heater core is a B to replace in that truck. Basically the dash would have to come out.
Can you do a video on polishing and port matching your intake also matching the proper cam ,cam lift duration and lobe separation to match the 906 vortec head with 202 160 valves oh and selecting the proper carb set up cfms and what not and if you have time add in the proper ignition . My 358 4 bolt is ok but I seem to be stuck at 435 hp im wondering if I'm missing something
This is going to be awesome! Very excited to see the results. I remember a Magazine article where Joe Mondello took a stab at porting vortec heads and he got basically no improvement. If we see north of 250 cfm at .500 on any of them I will be impressed.
With a little cleanup work and decent valve job those Amazon 200cc heads flowed 265 cfm @ 0.600. Mine were assault racing and dual drilled for Vortec bolt holes. After Lloyd Elliot ported them they hit 299 cfm.
Carnt wait for next installments to this . I was just about to buy some dart iron eagle vortec heads , but i mite hang off untill i see the your results . Cheers Adam👍👍
I would take a stab at the fully ported factory vortec . Please dont tell me its going to be the chinese knockoff ! Looking forward to these eps . Cheers from Oz 👍👍
TH-cam channel Rambling around has used the 200 eBay heads on a couple of different combinations, very helpful people and could possibly give you some more insight on those heads!!
@@cuttersperformanceif I was gonna wager, I'd put my money on The Darts taking top spot. Full port stocks 2nd. The rest is a toss up.... but I dont underestimate the Chinese heads. Ran a set on a in my 91 c1500 and for the money they were pretty decent. Running the summit dart clones now. Tbh not much difference performance wise imo. The summits are thick and beefy though and I dont obsessively stare at my temp gauge near as much 😏
This should be interesting, I’ve seen some work with bowl blending helping top end flow numbers but killing a bit of low flow numbers. But I guess that’s normal
With porting you can lose some velocity and that becomes evident in the lower lift numbers but im hoping to gain up top and still have a strong mid lift cfm We shall see! Proof is in the #s
I've heard a bunch of mixed things! But I couldn't help but be curious haha honestly they look better than I thought they would 😄 Wonder what they will flow? The ports look pretty nice 👌
10-15yrs ago the China heads were shit. But they've stepped up their game big-time. The KMJ Assault heads are the best of the imports. Same head Dart is using.
Is there a dual plane intake that fits ProComp heads, I can only get a Victor Jr, to fit, it’s got wicked top end, but I had to double up the gasket to get it to fit.
I am right at this point of buying after market heads. I am really excited to see this test!! I have heard the spring package on the China heads will need to be replaced before running any sizable cams?
That sounds great. But with a 64 cc combustion chamber your compression will be well above 10:1. Most likely out of the range of pump gas but it would be cool
@@cuttersperformance how do you think that cam will work. I want a split duration because I know vortecs lack on the exaust side a little and I want it choppy
Great vid and thank you for your time invested to do these vids. How do you feel about the 454 vortec? Curious on how much flow is obtained by manipulating the "ski jump"
I have not played with the 454 heads but the 305 vortec heads have the swirl port and I will have some flow videos with and without the swirl in the head coming up!
Hey I have a much smaller channel. Would you be intrested in doing a ported head shoot-out? We each port a vortec head and we see who can get the most flow out of them.
while i have zero interest in anything from china, i am most interested in Edelbrock Etec 170 heads. would be interested to see the stock flow compaired to stock vortec head and with each ported. I have read that the Etecs actually flow equal to or worse than stock vortec head which is hard to believe that a company would plow so much time, energy and money in to a product and gain nothing. i find it very hard to believe that Edelbrock does NOT offer a cnc ported version of the Etec head.
I've been curious on flow #s on the Chinese heads and I know others have been too because I get emails from guys but rarely ever public comments becuase I think guys are scared they will get torn up haha. I have a set of etec 200cs on a engine currently and only have the factory flow #s as i didnt flow them myself but I will compare them in the upcoming video to stock vortecs. Some really good flow info coming up! Real deal info! No hear say and forum facts
Didn’t see the EQ350 R in this data base of head flow, but know the 350 I is for stock replacement use in IMCA hobby class. www.users.interport.net/s/r/srweiss/tablehdc.htm

Lots of good info i think for diy'ers. But could you make a detailed video of reducing valve shrouding on vortec heads please and thank you.

I will be quite happy with 250 cfm on the vortecs but we shall see!
Whos going to laugh if the Chinese heads take the win? Haha

Nice videos.
I’ve ported vortecs since 98-99
keep up with what you’re doing.
Thanks for making this shootout, i cant wait! Also i would be interested in a comparison of Vortec carb intake manifolds...USA vs. China.
I'm also curious! I will start collecting some intakes haha

Great info, great channel. I can't wait to see your next video, always excited for useful information and knowledge. Keep it up👍
Thanks brother!
Looking forward to your video's. I'm interested in the gains on the Vortec stuff. Much better with a tri-pod!
Ron. Was gonna tell you about this channel. Guess I won't bother.
It's about time I poryed my 906s but still puting the engine together
Great vid!! Cant wait for the results. Happy new year ✌
Happy new year!
Any guesses the the best flowing to the worst flowing? I'm curious to see what guys are thinking 🤔

Try racing head service in state of tenn.
Yeah I talked to EQ again
They are a old casting from New Zealand
A mix between EQ and RHS
Dart, Amazon, your ported vortec, ehr, 2.02 vortec (top to bottom).
Will be very interesting what u find out!
Have you flowed the 416 305 HO heads with the 1.840 and 1.50 valves id like to know what they flow at?
Is there a dual plane intake that fits ProComp heads, I can only get a Victor Jr, to fit, it’s got wicked top end, but I had to double up the gasket to get it to fit.
Do you mind if I ask who Bill is that you refer to? I know a Bill that is a genius with Vortec heads but we have lost touch.
I am right at this point of buying after market heads. I am really excited to see this test!! I have heard the spring package on the China heads will need to be replaced before running any sizable cams?
Yeah I bought the heads bare so I could add my own USA Made springs kit and valves in them 👍
Can’t wait for this I’m wondering the best things to do to my 906 vortec heads before I put them on my 408 small block
That sounds great. But with a 64 cc combustion chamber your compression will be well above 10:1. Most likely out of the range of pump gas but it would be cool
@@fukemallgarage it also has flatops in it but I belive I can get away with it. It will be around 10.8.1
Can choice will be key, remember dynamic compression and cranking compression will tell you if it will run on pump gas over static compression
@@cuttersperformance I need help the cam I was looking at is a Howard’s 112141-08

What head gasket would you recommend for just a stock L31 with 062 heads?
If your looking for std thickness and for a undecked block
Felpro 501SD work great 👍
Seal well on a not so perfect deck

8 1/2% gain my guess
