Is there a way to make the b2 head flow as well as a6 swap or h22 head swap? Or just small increase?

 

port and polish. send it off to a shop that knows what it is doing, let them know how radical a cam you have and your compression etc, and make sure they send you flow bench numbers.

 

Probably cheaper to buy any 90-93 PT3 head (F22A) and have the same work done to it. You would get twice the flow for half the work......

It doesn't have to be an A6 head. All 90-93 F22 Accords used the same head casting PT3, the difference is in the cam and valve springs. These parts won't matter if you were planning on building the head anyway.

 

Lookin for at home work but thank you, possibly but lookin to keep same exhaust and intake
