We didn't heat em at all, a Lil oil... not reusing the stock pistons. Ever. They're smelted by now probably.... was a prepped block. Rats got into the building, ate the bag, and built a nest in the lifter valley.... was hot tanked, w/ a new 030 bore, new cam bearings...a Lil wire brush in the lifter bores cleaned em up really good, may have to get a silicone dingle hone. definitely need to CLEAN THE HECK outta the rest of it. I'm kinda pissed about it. That what happens when you let em sit for 15 years.
