Exhaust flange gasket

[clazar]

New 440 a month ago with new exhaust flange gaskets. Already one has blown out. What are the best gaskets to use with stock exhaust. Someone suggested Remflex. But they don't list for a 440.

Stock engine was without a gasket. Did you check straightness on both the head and exhaust manifolds before install ? You're using decades-old parts, I presume.

Do they list it for a 383?

This is for the exhaust that mates exhaust pipe to exhaust manifold.

This is for the exhaust that mates exhaust pipe to exhaust manifold.

Flat flange and not doughnut I presume?

A friend with a restoration shop only uses these Mahle gaskets for the head pipe to manifold connection. The metal ring expands when it heats up, to help to make sure you have a good seal between the two surfaces.

Flat flange and not doughnut I presume?

No donut, flange only.

I've struggled with this problem too. The gaskets like Moes has above are typically best. They have to have the steel ring in the center. If not they almost instantly burn through.

Send remflex a email they do have the gaskets and they work great.

These are correct for the 383 HP / 440 HP Exhaust Manifolds
