As long as your manifolds are straight, the Felpro gasket is just fine.
Never had a problem with those.
Running just a soft gasket tends to hard, get brittle, then blows out, that is the reason for a nice metal stacked gasket such as Felpro's.

I've tried several felpro metal gaskets and they never sealed. Never tried that "copper sealant" stuff I've heard of though. lol
