my engine currently is an f22b2, but i have a f22a head. Now i picked up the f22a head and plan on swapping it on to go along with my build because everyone always tells me they are the best flowing heads. But I am going to do a little DIY port and polish of the heads with my dremel; excluding any ****ups i could cause, if i ported and polished and smoothed both of em up and did a good job.... would the f22a head still be better? or is the f22a just better stock?

I know the f22a head does have .1 cc less head volume but i dont think that would really play much of a factore

 

Practice on the B2 head and then port and use the F22A head. If you port them both the same amount the F22A will still have a better flow the b2. It's the geometry of the ports not the condition of the port walls that makes the difference between these two heads.

 

thank you ghost. And oh yesss i am gonna practice some, im gonna get a junker head from the junk yard and practice. Out of curiosity do you know what kind of difference there is in the two flow wise? Besides geometry does anyone know what kind of flowbench results each one stock would bring?
