I've researched it a little, have a pair of 317 heads that I want to run so I can run more boost also. From what I have gathered the majority of people run the GM MLS gaskets, very good and pretty cheap. I plan on running them myself.

GM MLS or cometics. I havent had problems with my cometics but they are pricy. Get some head studs if you haven't yet.

Did you stud yours? Can it be done with the engine in the car?

I used standard MLS GM gaskets with o-ringed heads and they worked well.
The machine shop placed the o-ring in the groove on the gasket and it helped out tremendosly!

cheap felpro ones with a light coat of spray paint on them. They will never blow and you'll have to chisel them off to remove them. In a sense they are glued on. Cheap and very effective.

Never Blow, Maybe, but I bet I can lift the heads and make them leak!

LOL!!!! Yeah give me a crack at em', I bet they will be begging for mercy!
BTW my LS9's were sprayed with copper coat, and were glued to the block pretty well, in every spot except where I blew them with the aforementioned death cocktail.

"Never Blow" is a term that I would not use in the racing world!
Everything is capable of blowing!
