Better Plenum Gasket?

[6.5 Detroit Diesel]

I am wondering if anyone knows of a good brand name gasket for the plenum to intake? Mine is newer, but is leaking a little under heavy boost. It is a Felco gasket. Is there anything better? Maybe a bit thicker?

Did you mean "Felpro"? If so, that's a good one. Unless there is something actually wrong with the gasket, I'd guess that either the bolts aren't torqued right, or there is some old gasket material still on one of the mating surfaces. Did you use gasket sealant, or did you just put it on dry?

I had just bolted it up dry. This was a different plenum to go with the GM-3 turbo, but I had given it a quick glance and it looked clean. I might have to recheck that.
