Somebody have a /6 in at Maurer's Performance prepping for a turbo build?

So here's the build:

engine:
stock iron block over .60
stock '71 iron head w/ 3-angle and 1.7"/1.44" valves and pockets cleaned up
comp 264 grind
offy intake w/ water jackets
arp head studs (should i get main studs before assembly?)

i think mains are like rods... you need to have the mains line honed as they have more pressure against them, making a tighter fit...
