are there copper gaskets on the market fitting the Griff 500? The standard manifold gaskets don't last. Changed to copper with the 440 Mopars in my Jensens - best results. Thx Chris
I assume you're talking about exhaust manifold gaskets. Clever Trevor sells some OEM embossed steel composite gaskets that are the best ones I've found.
Or use sealant designed for the job out of a tube. Cheaper and no chance of excess material blocking flow (and creating extra pressure on the joint...).
