are turbo head valves stainless (or at least better than dual plug valves)? i'm basically looking to foolproof my dual plug engine as much as possible so i can increase the boost and make mo powah without breaking much. i'd like to do it as cheap as possible (esslinger=out of the question unless absolutely necessary). if turbo head valves are interchangable with dual plug valves i could swap them and be able to handle more boost right?
thanks
