Incredible. Basically 206cfm@300lift, close to 250@400, close to 280@500, close to 300@600 from a TBI head. Step back and think about that for a minute folks. This Man is teaching us step-by-step more than any book, magazine, internet site/forum, or TH-cam channel ever made. I have a stack of Mr Vizard's books also, but have never seen anyone share port development like this. Thank You for all that you do Sir!!!!!!!! We are watching and learning!!!!
Absolutely Correct Happy New Year In 1988 I was doing steps like your doing to show my old mentor what happens. Only people like you understand and learn plus teach. Keep enjoing
Yet another victory! Congratulations for making the port happier Charles! Those 'professional' head porters you mentioned, won't most likely choose to challenge porting the 'worst flowing' chevy head in the history either. This has been a marvelous journey of excitement and learning of this and that about port flow and porting in general. I'm looking forwards to the next 15 to 60 episodes on the same port, What ever it takes :) Thank you Charles for being an inspiration for us!
Certainly have to give you credit for sticking with it. 31 cuts into a cast irion head is an insane amount of work. All the trial and error with valve sizes and angles. You make it look too easy lol. Its certainly not. Keep up the great work bud. Im pretty sure i speak for most of your followers when i say we appreciate you!
Great results Charlie. Happy New Year to you and the family. It's already New Year here, and the year has significant room for improvement.... too much beer last night lol😅😅😅
This is great R&D!!!! 300+ cfm from the heads people throw away!!! I'm voting for the next combo to be a 2.055 or 2.08 on a 50 cut, and a 1.5ex on a 50
I can't believe you're getting these kinds of results from these things. Nice work! I wonder what the cost would be to replicate that work in customer's heads?
So Charlie, I've been watching this and pretty much just watching and trying to learn, but I was wondering a few cuts ago what would happen if you just took the whole ramp out and make it a "conventional" bowl design, wouldn't it be funny if it flowed more?
Incredible Charlie! You need to digitize these ports at some point, find a subcontractor CNC shop, and market the ultimate sleeper 600HP+ SBC head. You deserve some money from your great R&D on this! Or just figure out the best bang for the buck on material removal and manually port them. Based on min cross section at the pinch, can you calculate the theoretical peak HP RPM on both a 350 and 400ci combo? I was advocating removing all the obstructions in the bowl in the beginning.... Seems closer you get to a conventional design, the better, but now I see potential advantages in finding the ultimate bowl vane to induce the correct amount of swirl. I'm also wondering if this last cut was improved by removal of the hump, straightening the cyl CL runner wall to bowl transition as much as the vane mods?
Honestly you could do more than one version. You worked your way up to this methodically. There was plenty of cuts with other valve sizes that would make for an awesome street head. I said it way back when you started on this project. I Would love see the more milder versions with a tpi. Could be a efficient TQ monster that still knocks down killer mileage. Love it. Interesting as always charlie and happy new year bud.
Glad “Crash” is on the mend ... I absolutely enjoy what you’re doing with these 193’s .. I lightly ported a set many many years ago with good results but nothing like what you’re doing ... Have you done a port mold yet? Keep up the great work
So you said it would take a professional 2 cuts to get this done but yet no professional has ever tried to do anything with these heads(that anyone knows of). Also when anyone even "professionals" develop a port to have digitized, it's going to take more than 2 cuts.🙄😁 Which brings us back to digitizing those and marketing them. If you go this route try to find someone to back you so you can buy up those cores while they're still cheap🤔. After you put those on the market, the price of the cores for those are going to douple.😎 Like you said it probably wouldn't be worth it if you had to hand grind every set to sell. But a CNC program would handle that job in a fraction of the time. Probably won't make you rich but if they can be sold under their competitors it might just be profitable? Anyway, I wish you and your family a very Happy New Year.😎👍
They wouldn't even consider putting in the emense amount of time and energy into making these "junk" heads work. Especially because cast iron lol. These days finding a good head porter that ports cast iron is very difficult let alone someone as nuts as charlie to take on this project 😆.
@@bobbyhaskell2048 You sure there are no cast iron head porters out there that wouldn't want to monetize on this? Because I CAN think of at least one off the top of my head. Happy New Year.😎👍

That's for certain. He's a gem.

Funny! And probably true.
AWSOM job Charlie. It is interesting what the position of the ramp does. HAPPY NEW YEARS!
Happy New Year!
That's awesome . heads working phenomenly. glad daughter is on the mend ..get her a truck 😁😁
She wants good mileage...hahahaha!
Sounds like we need to investigate more into that L29 head.
It will happen. I have some 781's and 840's to compare to the l29 as well. Thanks

Thanks! It is a stupid amount of work no doubt.
Nice Charlie, like the way it keeps flowing more all the way to max lift
Pretty cool...
Ur doing what ya love brother
I am. Thanks
Great results Charlie. Happy New Year to you and the family. It's already New Year here, and the year has significant room for improvement.... too much beer last night lol😅😅😅

Happy New Year!
Don’t ever stop!!!! I don’t drink and can’t tell you who’s on any Football, Baseball, Basketball teams Want to go quicker and faster.
Mike
We are on the same team!
For the results of this 31.cut, I wonder, would the port with 1.94 valve see any flow imrovements with this short side and swirl ramp work?
I agree! Thanks
What's the max rpm you could get out of stock 193 heads
Best these have looked since cut 23!
Like a sine wave!
The 96-99 L30 305 vortec has a ramp in the bowl like you're talking about going to, like the L29 bbc
Exactly what I was thinking.😎👍
I don't think I have ever seen this head. Good info. Thanks
Hmm, nice job.
Thanks!
I can't believe you're getting these kinds of results from these things. Nice work!
I wonder what the cost would be to replicate that work in customer's heads?
More than it is worth. Thanks
What would you charge for a set of bbc bow tie heads and a set of vortec

It might but it would probably lose the swirl. Thanks

@@bobbyhaskell2048 No doubt! Thanks
@@bobbyhaskell2048
You were the one that asked who would waste their time with these, now you're doing a 180, what's up with that?
Great work Charlie. Can't wait to duplicate this the best I can. Your a legend! From New Zealand.
Are you going to work your magic on the TBI intake as well?
I have two tbi intakes that are worked in stock. I need a a stocker to compare. None available here. Thanks
@@servediocylinderheads incredible work on those heads, this series has been fascinating to watch.
@@jimmy_olds Thanks!
That is the plan. I see one local I am trying to get. When we flow the stocker there will be crying.

No molds!!!!
Man those would work on a 427 small block and make big block power
It would be fun to try. Thanks!
This is better at every lift point than a trick flow 215 LS head except @.600
Funny!
Idk how many sets of these i threw in the scrap yard 😅
Yeah, I hate that.

I love your stuff Charlie and I'll keep on watching but I gotta be honest, these heads lost me at cut 21ish. Still getting nice numbers tho... 🤔
Lost me too!
