You really are hard to understand Justin, and I don't appreciate your snide little jabs even though they are barely comprehensible gibberish. "Though I know it all" ??? If I knew it all I'd sell you my dyno and flowbench as I wouldn't need them anymore. Also I never said "these are the 1st fact iron heads ive ever taken this far before" What I said was I've never had a customer pay to have factory iron heads ported and then strapped to a high compression 416 before so I was very interested and not all that sure it would make the 500+HP goal<<mainly because I DON'T "know it all" . Wish you had more to contribute because people like you make me realize sharing is a waste of my time better spent elsewhere. J.Rob
