How long should I wait to install it after that? 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual

I also didn't scotch brite the gaskets to help the silicone stick to it. SCE has some copper head gaskets that are .032 thick so I think I'm gonna try those. My pistons are .016 in the hole and last years Summit copper gaskets were .043 thick so quench was .059. So with the 32's I'll be at a better .048. I'm headed to Superformance right now to pick up some oil pan gaskets and show Greg my Summit copper gaskets. 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual

Now I have to decide what sealer to use as you guys have given several great ideas. I was leaning towards the one that 'Instigator' posted but RoadHazard and a couple others have told me that Hylomar or spray hylomar is the way to go, then there's also this Yamabond. 1970 Challenger, all aluminum 528 Hemi, HDK suspension, Tremec 5 speed manual

Nice to meet you and the wife Bob Use Yamabond if you want to take them off with a BF Prybar Hylomar is a non hardening and much easier to work with. It's been around for years in the aircraft industry. They used to apply it to aluminum engine cases and seal them with pure silk thread, that's it!
