I've got a spare LA 360 block in my yard and just read an Engine masters build where they built a stock displacement 318 and made 425 hp with Engine Quest lightning heads (magnum design),new pistons,cam and an eddy rpm air gap,I'm just trying to get opinions on whether its worth swapping the heads or just get a set of rhsXindy heads,and what kind of numbers can I get from a similar build with the rhs iron heads.
