Best sealing LA Small Block Header Gaskets?

Which brand of exhaust header gaskets seal best for a 360 LA Small Block? Thanks.

clean head and flat flange and I've had good luck with about anything out there.

My tti gaskets that came with the headers have been on for 10 years without a leak, probably due to the header more than the gasket.

I got some jacked up headers on the Duster, I used Remflex they are quite a bit thicker and a bit spendy

I like the tti gaskets.

A good thick flange of 3/8" and I have used the
MP grafoil.. also one of the bolt holes per tube
enlarged to let it slide .. and a coat of hi temp
silicone

Hands down these... Multi layered soft aluminum. Seal fantastic on my turbo car with huge back pressure compared to an n/a motor.

I like cometic gaskets, hold up to the nitrous heat no problems.

TTI gaskets on mine for 8 years or so.

Appreciate all the great advice, recommendations and tips.

Thanks Again

Anyone know if any of these products can be had in bulk? I have to hand punch mine, as they are one-off.

These are the best that I've found.

You can buy Remflex in different size sheets. I see it on Remflex's site and on Summit's.
