Gonna be putting the heads on my 355 tomorrow night. Do I need thread sealant for my head bolts? I have read horror stories of studs leaking after bolting the heads on and I trying to avoid this problem.
I have AFR 195 Eliminators (old style) going on a 355 that is fresh out of the machine shop with a set of GM Impy gaskets. If you guys think sealant is a good thing to use, what sealant do you recommend?

I dunno, with alu heads I'd think you might want to use it more than with cast irons. That's just my train of though though, based on the alu's expanding and shrinking characteristics.

I've always used Permatex High Tack. A bud has a blown SBC and had some leaking through the head studs when using the ARP sealent. He switched to this Permatex stuff and the leaks went away. Nice and sticky-goopy.

AND it has a brush!! That's what I used on the last SBC I slapped together. Like Speed said, be liberal as hell. If you want to, just dunk each bolt in the can
(personally I think that's taking it a wee far heh)
