Wondering if that's good on my intake manifold and oil pan ?? Thanks for posting this helpful info

I believe the vapor blasting will leave too shiny of a finish on the typically dull porous aluminum surface finish of intake ,oilpan and open letter valve covers. It looks good for many other things however including some other aluminum parts just not rough castings IMO.

The set I got from Burgy in 74 or 75 were sealed in thick poly that had turned yellow. When I stripped the stuff off the highlights were polished, not machined.

Considering the date and the source I'd say they were unmolested but it you want to consider that an anomaly I won't argue. I have nothing to gain by being right.
