well my question is im gettin told boosting the f22b1 on a head is crap, like the head flow is crap as i have been told.
So im concern on what to do on improving the head flow?
Like theirs a machine shop that can do porting and i want to know what to do say when i take it to the shop. Like i have h23 IM manifold and i want to get the intake ports matching the manifold.
But what else can i do or what do i say to the shop on porting the head?
Do i just say port this please lol, or do i need to give a certain dimension or measurement for i can get a proper head flow.
My goal is boosting down the line being able to adjust from 7 to 10 psi. BUt i want to take care of this i was told just get a f22a head but ill be losing power like 15hp or something.

 

keep your head and do a little more searching on boosted f22bx's. the stock head is fine and there are plenty of guys making 250-325 whp on stock heads. boosting anywhere from 7-12 lbs. some guys boosting up to 15 psi with good tuning and proper fuel upgrades..

 

stock head on 12 psi makin 305whp, get her port matched and get the vavle guides chop even with the ports make sure they have a flow bench before you have them do it and ask to see it to make sure that there not just saying they have one, runa stage two cam and cam gear
