I just did the work and showed the results of how it reacted to it . I let it decide what it liked . It loved a back cut exhaust , it only wanted a single 45° cut on the intake.
I had a set of these on a 408 Windsor, 10/12 to 1 with a comp roller cam. I picked up almost 140 hp when i switched to afr 205s. In my mind these heads are definitely not going to get you big hp out of the box.
I agree, much better than stock , but it cannot compete with a cnc ported set of heads like an afr 205 or a set of 205 11R heads , especially unported out of the box . But at that price point, fully rebuilt stock is in that range. Lighter and much better flow than stock stuff. If someone wants more power potential, port them or spend around $2k + for a better option. Thanks for the update. 👍
Thank you sir. They ended up right at 200cc intake runners. I don't remember the cross sectional area. It is a 2.02 1.60 valved head. Mine are from skip white, NKB heads, AFR also sells them under the 185 enforcer name. Of course you pay more from them.
@@mylanmiller9656 the flow data I have for those heads shows peak flow at 215cfm In 179cfm Ex and 170cc intake runners. The data suggests lower horsepower with a 37cfm intake flow loss with edelbrock performer heads . You would have to step up to a 165 or185cnc head or a as cast 205cc head for more horsepower potential .
@@blueovaldude thanks that is nice to know! i was running the Performer RPM heads but during my last freshen up We found a bunch of Cracks! I bought the Set of NKB 274 heads for less than the cost of 1 Performer RPM .
@@mylanmiller9656 If you are not afraid of doing some mild port work, I would at least work the exhaust side . Check out my earlier videos if you are interested .
It's good to see someone doing the right things when they are porting heads good job on your work and your video👍
Thank you sir , glad you enjoyed it.
liked and shared been sub for many yrs. xl
Your valve back cut commentary is the exact opposite of every single professional porter in existence.

Great job! Those are some impressive numbers out of affordable heads
Thank you , they turned out better than i expected them to .
Nice work and flow numbers! I like that you showed that slight mods can have a big impact on flow #s. Nice Intake short turn. XL
THANK YOU , Appreciate it!
I'd love to see the porting on the intake!! Thanks for the videos!!
Thank you sir , we shall see , perhaps.
thanks for the videos! XL i have those rockers, havent used them yet
Those heads should make big power. Nice.
We shall soon find out ! 😀
Liked,shared,subscribed!
Large. Thanks - good video!
Thank you sir .
Great job. Xl
I hope I'm still entered in the drawing for the shirt because I followed your instructions on the video you did on the rockers when you first got them
Yes sir , all good !
IAM gonna send a set of nkbs your way for you to work your magic on! XL
Haha thanks , I wish I could help you out .

What port volume and cross section ? What brand heads ? Valve sizes?
50 cfm gain is great

Check out my cylinder head porting videos to see what i did and how i did it . 😀
Did you run the NKB heads out of the box ,if so what kind of power did you get!
Out of the box , i only put them on the flow bench to see if their advertised numbers were accurate. I didn't want to use my dyno time for that .
@@blueovaldude I was curious if they would match the power numbers a set of Performer RPM heads!

Maybe it was you...
I've been trying to remember who said that the push rods were heat treated on only one end from Ford...
Was it you?
No sir , that was not me .
@@blueovaldude
Ok, and if you were not aware of that, you can hear the treated end when you tap it, and they are supposed to be at the rocker end.
dyno!! i know it's coming.. lol
You know it !! Lol . A few things to finish up first.
