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.
