does anyone know what head gasket to use with the gt40 heads to keep the compression ratio at 9:1?? i can't seem to figure out what one i will need. thanks guys/gals.
so with the gt40 heads there's no change in compression ratio then? cool. thanks!! that helps out!! no when you say stock, do you mean just regular mustang head gaskets? sorry to ask, but i'd like to only do it once if you get my drift, don't want to screw anything up. i'm not new to working re-building engines but just not familair with swapping parts from other cars ect....
