Cris- Duane brought up a good point about taking off the heads while in the door car with head studs..it could be a challange..to the point of having to yank out motor or at least pull forward..
if ya wanting the extra sealing power around the cylinder then i would check into the FEL-PRO MLS head gasket's..about $200 for the set and use head bolts the closest thing to o-ringing a block without doing it.
( i have a little un-fair advantage of your situation then most people cause the motor use to be mine)
so i know your motor pretty good LOL...unless your gonna spray the thing or convert it to a blower motor and pack the cylinders i would not sweat the head studs etc....the copper gaskets are great as zip said for re-use but my opinion on this is Copper head gaskets are a great match for a o-ringed block,head studs and of course a good dose of Hylomar..
can you use one without the other...YES!...but its like swimming with your clothes on...lol :roll:
the motor has ran for 8 years with Regular Fel-pro head gaskets and head bolts at 13 to 1 compression..
just my take on it.
