Big thanks to everyone who contributed to the thread. Helps answer a lot of questions. For reference on the case I recently did for my '79, I did the left half.

>1194 on the case perimeter
>574 on the bearing saddles
>Dow 112 paste on the #8 o-ring, dry bore
>Dow 112 paste on the green thru bolt o-rings, installed next day one at a time.
>Crank seals both installed "dry"- a little bit of spit on them to ease going in the bore

I like the 1194. Goes on well and smushes out oh-so slightly. Nice.

My work was on an engine that was assaulted with 574. I hate the stuff for clean-up. It was on the case halves (probably both halves), on the cylinder base gaskets (what a mess), on cam towers to heads (probably both mating surfaces as well), on breather cover gasket, on cam end gaskets, on intermediate shaft cover, on oil cooler seals. Like I said, what a mess.

I find it surprising in the thread that a lot of people questioned the benefit of the 574 on the main saddles. The evidence is pretty obvious when you look at the mating surfaces of the saddles. That "hatched" grayish-black finish you see on them is not from machine tooling marks. That surface is fretting caused by the two surfaces rubbing back and forth against each other oh-so slightly.

The 574 helps prevent that. Next best solution is shuffle pins but who needs that on a stock rebuild or mildly warmed over engine?
