I use the Mr. Gasket with the metal sandwiched in the middle, haven't blown one yet........just make sure it's the right one, oval or square port....just my choice, but prolly not the "best" choice....
I have good luck with Fel-Pro's and a little Ultra Copper goo smeared on them. For the first few days retighten the bolts after each drive, and you should be fine. The problem a lot of times is the gaskets compress, the bolts get loose, and they burn through--If you get them snugged down after they have compressed, they will last a lot longer.
I have some fancy Percy's XX Carbon gaskets, and some of their dead soft aluminum gaskets, but haven't tried them yet. The carbon ones are supposed to withstand constant 2000° temps!
If your heads have stock ports consider using exhaust manifold gaskets. That's what I'm currently using, they re cheap, can buy them anywhere, don't blow out ,bolts stay tight and I've had the headers on/off several times and they still seal up.
The ones I bought were made by fepro and had slots instead of holes so install was easy; put all the header bolts in loose then just drop the gaskets into place and tighten.
I used to use the old thick white paper Mr. Gasket ones and would soak them in water. Bolted them on and made sure to tighten the bolts evenly and recheck them after a good heat cycle. Now I use the blue felpro performance gaskets. Always make sure the header flange surface is flat and don't over tighten the bolts.
I have been using the same gasket for over 3 years, and had the headers of and on a few times.
I am very impressed with the Fel Pro Performance steel laminate gaskets.
Fel-Pro Performance Exhaust Header Gasket Sets
A good seal from Fel-Pro.
Fel-Pro Performance exhaust header gaskets are made from high-temperature, high-density fiber material around a perforated steel core, for durability and heat resistance. They're pre-coated for easy removal.
The Percy's aluminum work great. I wasn't a believer until I tried a set. I've had them on and off about 4 times with no issues. I also use header studs and never have to re-tighten the nuts.
just my .02c
