Media blasting parts like this is a common cause of assembly failure down the road.. media gets into blind holes, casting cracks, crevices and other places, and if pressure is too high, the media can embed the soft aluminum surface, all of which is not easily removed with compressed air or cold water.
Then once that aluminum case (or other parts) heat up, spin, vibrate, that media comes out to play.
Most race shops, Aviation shops I know of, the media blasters are not allowed in the same space /room/ building as the engine building space as they know you can not control the media to a great point unless its a positive pressure ventilated clean room kind of deal.
The poor mans fix post blasting is heated liquid wash.... can be a heated sonic tank, heated water pressure washer, dishwasher, heated aqueous parts washer or the like...
Or use a media like soda, that dissolves in water and you can wash the part with a hose after and get great results..
dry ice blasting is also a safer alternative than glass bead or other dry abrasive blasting

[QUOTE=E.Marquez;405660]Understand I hope you just stripped the protective layer of anodizing off the aluminum... and for post abrasive blast, PLEASE hot wash the case..
I had the cases all taped with masking tape, the cylinder heads, all the bearing surfaces were covered. I was really just attacking the areas where the painted aluminum had gone punky. I intend to paint the whole engine once I get it all together.
Thanks for your input. I will be hot washing the case once I get all the parts ready to assemble.

Got a box in the mail Part II continued
I got home this afternoon....and I was bored...so I decided to make a wooden frame for the block, so when it comes to torquing the bolts down on the con rods and putting the two halves together I will not need to ask the wife to hold the block. I do not know what you guys do when it comes to reassembly.
