honestly i wouldnt bother unless you want to but as staded before it will have to be checked for flattness and if its warped milled down id just throw the studs in, if the gasket isnt bad it doesnt need replaced

yea id just throw studs in as long as ur not going much over 45psi on ur turbo, i was getting aay w 50psi but thats me, if ur not planning on really beefing the motor then just take about 2 hrs and take one stud out and replace with a new one, and idk about everyone else but i did my friends and i tightened down the new studs at the required factory spec in the sequence then when i had all the new studs in i followed the sequence again and tightened the studs down to the required ftlbs of ARP.

Well just sold my other truck I had head studs and a marine head gasket just like mine now and I was pushing 60psi w no troubles.. I wouldn't recommend much over that but I've seen ppl pushing more...
