Mitch1, how did you get your aluminum parts so clean and with no visible black oxide.? Are they in natural finish or did you painted some of the components? Please share your engine clean and finish procedure. The result was amazing, even the engine power area looks, brand new, mine is all dull and with an dirty off-white shade.

Thanks. Can't take all the credit though. The case was hot tanked at Ollie's. If I had to do it over I would've had them tumble it to. Most of all of my cleaning was done with small stainless steel and brass brushes from Harbor Freight and lacquer thinner with a good dose of brake cleaner or carb cleaner. Used Kim wipes and industrial q tips I got at Northern Tool a lot as well.
On a side note. I spoke with Tom Petrushka at Mayo's Performance at length about engine rebuilding and common issues with rebuilds. He advised about the leak between the heads and cam towers was something he's dealt with before. His answer was to heat the heads after bead blasting in an oven. He said the oil soaked into the aluminum is then heated and cooked out. I think it they would've sealed with Threebond. I'd never use aviation permatex after seeing how much it runs when hot. It plain looks bad too.

Work of art Mitch.
