i ordered bbk longtubes with their ory. i bought a pair of felpro exhaust manifold gaskets. are these ok? or when i order my o2 extensions should i order some gm gaskets? also i am planning on using new stock replacement bolts. those allen headed bolts look like trouble. i know this is probably somewhere but i have been searching for the last couple days and cannot find a 100% forsure anwser.

Thanks,
Sam

EDIT: also what size freeze plug do i actually need? i've seen 3 different size from search.

Get the GM gaskets

Any particular reason? Is there a difference? I don't mind the extra cost just curious

I think any MLS (multi-layered steel) ones will do the job. Just don't put the crappy paper ones in.

These are steel, not sure if there MLS but they sure aren't paper. They look half decent, was just curious whatvthe difference was between 2 steel gaskets?

GM mls gaskets get my vote, those arent bad but for alil extra you wont have to worry about leaking.
