Default head gasket selection

need help choosing head gaskets...in the process of "freshening up" my 525 sc....its getting a set of dart heads roller cam and 575 sci blower...whats a good choice for head gaskets?? it will have ARP head studs installed as well...may seem like a dumb question but I know not all gaskets are created equal

thanks

Need to know more about the setup to recommend an exact head gasket.... desired compression ratio, piston cc, head cc, etc.

I would highly recommend an MLS (multi-layered steel) head gasket though, but I cant make a recommendation on brand or thickness

you don,t need a mls gasket for you,r power leval,a fel pro perma torque would be what i would use.edit in,i also would not use head studs,arp head bolts would be a better choice.

You need to have heads and block machined to a finer RA for MLS gaskets.

so maybe just stick with the felpros and hope for the best??

What about this...lets say the engine had 9:1 compression...how does that change things??

The Felpro marine gaskets will be fine. I ran them on my bumped up 525SC with 8# of boost.

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?

I also just used ARP head bolts and not studs on mine.
IMO, studs are overkill for what he is doing and he will most likely have to grind the lower studs to clear the exhaust.
