Head Flow Numbers
 

A great resource when deciding on a set of heads.

Flow Comparison for Most Ford Heads

Thats some nice info:nice:

I stickied this so that people will not have to dig and search through the forum to find it. Very good info.

Thanks :nice:

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

:shrug: improved runner design maybe?

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 :nice:

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.
