Hey guys need some advise. i pulled the champion irons off and going to my gn1's,,,,what about my pushtubes(pushrods), what lenght will i be needing, or do i need to just measure them? if so how's the best way to measure for them,,,,,thanks
also what about my head studs? will i have to change them too?
head studs

on the head studs on the gn1's the 2 center studs are short,,,, is these the ones that needs to be longer looks like the rest of them will work. any info? i just hate to buy a new set if you dont need them
