I'm about to install a set of 350-60899 aluminum heads on my SBC. I've been told that some of the head bolts are gonna require sealing with silicone or something because they go thru water jackets. Anybody know which ones will require sealing?

All , i use pipe dope , locktight makes it, its liquid teflon like pipefitters use, comes in a squeeze tube with a nozzle that rotates to close, works like a hot damn gives good torque readings too and you can buy at any hardware store.
