Studs or bolts??

ARP of course, but...

Head studs or just head bolts??

Studs are more expensive, but how much stronger are they??

with what you are building, i would go with studs.

The only problem I have with studs is the heads WON'T come off the car with the motor in.
Otherwise, they sound like the best bet.

you plan on pulling the heads on a regular basis once you install it???

Not really. Although it kinda depends on the heads I get.
If I get the AFR 225's, I might want them touched up later on.

Who knows though...things can happen that require the heads to come off. I hope I don't have any of those kinda problems, but.....

well, you could always section the windshield funnycar style. with a fiberglass insert to take up the space ;)
