I need to know what good head gaskets are out there for a N/A 306. i have some that i got from summit, but i dont remember the brand or anything. ive heard of cometic? (sp) gaskets, but heard those are only good for blown/juiced combos.

-Block Bored and honed to 306
-Trickflow 10:1 forged pistons
-Polished crank
-Trickflow Track Heat Heads

I've never had a problem with Felpro 8548's or 9333's.

Fel-Pro 10111-1's are very nice.

A Cometic or Fel-Pro MLS gasket can be used far any combo but they require a certqian finsh on both the head and block to seal. They also give you less margin for error if you get greedy, they will not blow but your parts will break. I don't use those on any customers cars unless they have a good understanding of how to tune.

A friend of mine has been running a worked over 306 for several years at over 10.5:1 CR, with Felpros. Never blown so far as I know. And I would have definitely heard about it.

We've seen three different part numbers for the felpro gaskets. Can someone explain the differences?

The 8548's are a stock replacement gasket, around $17/each graphite pieces.

The 10111-1 are a Performance series gasket, composite material, stainless steel fire ring $31/each.
