I found this out "the hard way" more than 30 years ago, when rebuilding my first 350. Everything I read at the time gave torque specs for "lightly oiled" threads and said nothing about the sealer on the head bolts. I don't know whether it was just an over-site or they expected readers to know this?
Big mistake, cost me several hours to backtrack and repair...

Corrected sealant for old bolts, arp if I remember right has has some already on the bolt
