Thanks for the sticky Tommy.


It is interesting to me that GT-40 'P' heads flow better than the GT-40 heads that came off my cobra even though they have smaller exhaust valves

I had planned on swapping to AFR 185's for my n/a combination that I am trying to configure. After comparing them to my current 165's and the cam I am wanting to go with, I am thinking it may not yield much better results over keeping the 165's

Lee,
The 185's work very well on a 331-347 N/A combination.....

I know a guy running Victor Jr's on his 347 and he's running 6.5x's n/a. And they are cheaper than AFRs.

nice post

The discussion possibilities of cylinder head flow, port size, and power potential are endless and often pointless.

It's what works best with your combo ultimately.
