Intake/Exhaust Manifold Gasket

[AZJeff]

After my "0331" head calamity, I have now found that one of the OEM cast iron manifolds won't seat properly on the new cylinder head near the #6 exhaust port, and thus I have an exhaust leak until the engine REALLY warms up (like about one hour of running or more.)

 

So.....I bought new manifolds, but I am unsure what type of gasket to use.

 

The OEM type gasket is a composite of embossed stainless steel and some sort of fiber material, with the stainless steel around the exhaust ports, and fiber around the intake ports.   Another gasket I have laying around from extras when I replaced the head is a Fel-Pro one that is made completely of some sort of fiber type material.

 

So....based on experience, which type is more durable/reliable?   I know my new cylinder head from Clearwater is flat/true in the manifold area, and I assume the new manifolds are equally flat, so I am not trying to overcome some warpage.

 

Inputs/suggestions welcome.....

Remflex 10-001

best gasket hands down. Been running these since they came out

Thanks for the tip.    Looking at reviews of the Remflex part on Amazon, other Jeepers are saying the same thing about it being the best.

 

They pricey, but "buy once, cry once"

Just remember with the remflex gasket, you can only use it once. It is fairly soft so be careful when installing it. The graphite creates an awesome seal though
