ARP Head studs or bolts?

[gmsotaku]

The engine is at the shop, the head is bad so were getting a new one for $425 with cams. We need to start ordering parts soon, taking apart the 7mge we had head bolts, but now looking online and on the forums everyone says to get head studs. What's the difference? Has anyone here used bolts? Friend is convinced to use bolts, but I'm saying studs, (only because a lot of the rebuilds here, and on other forums use studs...)

Can anyone enlighten me?

Thanks.

FWIW, I used the studs on my rebuild because people said that they were better than the bolts. It's been 6 years since my rebuild and no problems to report. Unfortunately that's all I know.

From what I have read, boost goals above 12 psi it's best to go with the head studs. I searched for a few articles to back it up and cant find them.

i believe studs allow you to get a more accurate reading on how much you torque it down by. Also bolts stretch and you have to retorque them, i dont know about the studs tho

gmsotaku, Here are a couple of threads on this board that discuss the stud/head issue. Hands down, go with the studs:
