good to know griff thanks!! I think if I can get away with the cheaper route ill probably do that as im looking at buying a complete shortblock now possibly so no reason to tear it apart to have the head cleaned up just for the purpose of running a gasket that I probably don't need

IMHO: Felpro HG (more forgiving and you have mild engines) and ARP Bolts. Studs harder to seal in 454 blocks, studs can interfere with other things, plus the bolts will handle pantloads of HP. Pantloads = a schitton.

I'm sure a stock style head gasket will work just fine but I would highly recommend stepping it up to an MLS. Especially since you are re-doing everything you can have the heads and block finished to the correct surface finish for an MLS.
I cant think of any drawbacks to an MLS if done properly. I cant actually name a modern engine that doesn't have an MLS gasket.
Also, what is your reasoning for recommending head bolts over studs?

7-8lbs boost? Dart Heads? Chiller? Upgraded cam? you're gonna be spinning the bearings out of the 177 trying to get 8lbs of boost.
better heads, better cam, drop boost and gain power. Chiller is a bit of a restriction, and blower needs to be spin faster to overcome that. That tiny blower is gonna be working overtime for minimum wage.
imo, you wanna run 8lbs on that combo, get a 8-71.
As for head gasket thickness , as long as your Pistons aren't above the deck, a .040 gasket should be fine.
