Anything over 16.5 will trash a factory gasket

ive heard doing it 1 by 1 is better than pulling the head and getting it resurfaced and new hg since the old one has a solid seal?

It is the only way to do it if your not pulling the head.

i know that i mean compared to pulling the head and gettin it surfaced and replacing headgasket. is it any better to pull the head and surface it n all that or just replacing the bolts with studs 1 by 1? ive heard people on both sides of that arguement... i guess my question is why would it only hold for a while? is doing it one by one not as good in your opinion?
