This thread was invaluable to me when I did my motor. However, I didn't question the benefit of 574 on the saddles, I applied a light coat. Sheer strength is very high, so should really limit lateral movement of the saddles.

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