Thread: felpro or mls gaskets?

hey guys just looking for some opinions from y'all. I'm in the middle of building my car up throwing a s259 turbo on and blahh blahh, any ways I'm just trying to see what would be a better decision between the mls head gaskets with copper spray or the felpro ones(both with arp head studs). The goal is for 450-500whp on e85 and figuring around 15-20psi. I've herd of the felpro ones holding 700hp with arp studs but idk if anyone else has had any luck with high hp on felpro gaskets or if I should just figure out how to get the mls gaskets to seal and use them.

But how much power can you make safely before blowing the felpro gaskets on ARP studs?

600 might be an starting point for issues... I chunked mine around 700 but i was running way too much timing.

Do you have to do anything special with the install of the felpro gaskets our do you jus put them in like normal? And do you use Teflon tape on the studs or no? Cuz I've herd some say they do and others say that stuff don't belong around engines.

Any one herd of the fel pro perma torque gaskets?
