Post Head bolts?

i have a 79 350 i was wondering if i should use silicon on the threads of the bolts? Also do i put anything on the intake manifold gaskets? I heard you should put something around the water jackets is this true?
thanks

i wouldnt put silicone anywhere inside the engine. i use it in place of the rubber pieces on the intake tho, and you do want to put some sealer just around the water holes. if you use the rubber pieces you need a dap of silicone on each end. you know the drill

Bullheimer is right as usual!!!! The head bolts get "Anti seize" only. Do it!!! I agree with the bullheimer that if you use the rubber gasket(Front and rear) use a dab of sealant on the corners.I use them!!! Some guys say just use sealant. Not me, I`m simple minded enough to think they were made for a perpose. And the factory uses them, so shall i. I like to use a product called Indian head just to stick the gaskets in place.And as a sealant i preferr copper coat.Good luck.

we use a teflon paste on all small block head bolts it acts as a sealer and an antiseize also gives better torque readings.a small amount of silicone around the intake crossover ports.

ARP produces a thread sealer and has a different torque value if used. ARP head bolts also have different torque values when using either motor oil or moly lube. The thread sealer would be good to use when the bolts extend into a water jacket. If a hole has a bottom make sure there isn't any thread sealer or lube on the tip of the bolt, this could cause a hydraulic lok and bust a block around the bolt.

Yes! Teflon Paste you must seal the bolts on SBC and BBC they run into the water jacket.

I always use a liquid teflon...about any parts store carries it, comes in a little white squeeze tube. There is enough in there to do probably 2 or 3 motors worth. At only $3.00 a tube, you can't go wrong.
Later,
