Hi guys, I've been searching for information about this but the answers so far have been vague.

I'm looking to build up my F22B2. I thought about an H22 but i dont have the time and money for a full swap, so I want to do some head work instead. I came across some information claiming that the F22A head is much better than the B head. Is this true? If it is, what are the differences, do they bolt right on, and is it worth building up? With a quick online search I found multiple A heads at local junkyards for about $150.

Sorry if this has been answered already. If it has, I only ask that you point me in the right direction and then you can delete this thread. thanks.

 

does anyone have a solid opinion about this? my research has led me all over the place.

 

Me too! I'm thinking about putting a F22B1 head on my F22A1 block, because I hear the boosted numbers are better with the VTECH head from guys who put them on their stock A1 blocks. Then I hear that the B1 head is terribble for boosting, and that the A1 block offers better flow. Bump for a pro answer!
