which is a better head the f22b2 or f22aXXXXX? open to any opinions thanks

 

It all depends on what block you're working with....

 

the f22b2 block?

 

So far from what I have been reading and flow tests that I have seen. The stock F22A* have the better flowing head of the F series engines. And they will fit on a B2 block. IIRC they used the same block castings for the F22A & F22B.

I remember reading that one of the A's flowed better than the other, but I don't recall off hand witch one it was....A6 or A4??

 

stupid question but what does IIRC stand for

 

If I Remember Correctly
