When was the last time you saw one of these (mystery race engine purchase)

The washers like things are nylon or something like it. No idea on the white goop. Most of the engine fastners will go to the scrap bin

Are you familiar with line 2 line coatings?
I had my pistons done after the rings butted
If your piston clearance is over loose have them coated. It was just about the price of 1.5 ross pistons when I had it done.
