Remflex 13-001 Exhaust Gasket for Buick V8 400/430/455 Engines, (Set of 2)

On the GS, no more header leaks, that center bolt on both sides of a 455 is a pain, and the 2" primary TA headers would leak on the left side every time, so I took them off and used a Hooker gasket, which worked great, and now I hear other noises from the collectors. If I ever need this ride again, I'll purchase it again.

I was very pleased with how sturdy and easy they were to install. I had no idea how loud my manifold leak was until I installed the remflexbr>I was very pleasedbr>They were sturdy and easy to slip into place without having to remove the manifold completely. In the car, I made a substitution.

Last year, I installed these on my Buick 430 - I was impressed with the quality and am hoping they will last a long time.

Two other gaskets had failed to seal an exhaust leak, but this one did. Mr. Gasket or Mr. Pro.
