Need some expertise on cleaning up aluminum heads and intake manifold off a V-60 in preparation for Concourse division. Currently they are original casting finish, dirty and show their age. Thanks! johntesch@frontier.com

I am certain you'll receive a variety of opinions on this...here's my two cents: I always GLASS BEAD my aluminum heads and / or intakes. They come out looking beautiful and as new. The 'finish' lasts for years. Yes, I have numerous 997+ point cars to my credit...

With all due respect for Mike's always excellent advice, I believe I'd try to get them clean without being quite as aggressive. I'd start with media blasting with either baking soda, plastic media or walnut sh*lls. Glass beads, while not as aggressive as sand, do affect the surface finish, which should remain "as cast". There are also some shops that clean aluminum with specific solvents; (automatic transmission re-builders), that will brighten the aluminum without affecting the as-cast surface. Do not hot-tank in a solution designed for cast iron however, as you might come up missing some parts.
