Machined Heads & Rust

[Donutblue]

I was thinking the same thing, at least try it. They are 390 High performance heads. The guy that owns them went into a parts store where he is a steady customer. They told him they had them sitting in the shop for years, the original owner never came back for them. He left them in the bags in the barn, took them out of the bags in front of me, Probably sitting 20 years or so. -- He has a 390 motor wrapped and sealed in a plastic bag too, he said he covered the motor and cylinder walls with grease before wrapping.

Blast?? Why not just have them dipped to remove the rust??

Dipping wont harm machined surfaces.......

John, I did not think of dipping in a rust remover, but that may be the first approach, nothing to lose.
