RE: pi heads

GT40 heads are for 302 engines. there are no performance castings for 4.6 engines. PI is the best they get. you just need some porting cams and a s/c.

RE: pi heads

with porting, cams valves springs and bolt ons, you'll make 300 rwhp. don't know of any places in illinois, your best bet may be to buy a package from VT engines, and then sell the heads on your car now.
