Hey.. im running a b17a w/b16a intake/exhaust manifolds in my 97 civic hatch. I happen to have a b16 head laying around and am considering either sending it out for headwork or sending it in as a core and getting a built head. My question is what kinda power gains can i expect to get when i put this on my b17a? I have i/h/e plus stage3clutch and lightweight fly.. Also how much can i expect to spend? Thanx
