i have a friend with an F22 that would like his head rebuilt, he is shooting for about 300hp on pump gas. the motor might see 20-25psi one day/eventually.
so my guess is F22 head build, upgraded springs, retainers. And then whatever other suggestions you have on other parts/stuff.
He would like to keep the cost on the low side if possible.
Thx
