If that stuff adds any fake color to the aluminum, forget it!

I'd like to have a few words with the idiot who painted the spare set of Royal Enfield Interceptor cylinder heads I bought some years ago.

When I was restoring my Interceptor last year, the plan was to use those heads since they just needed the valves lapped in. The original heads were functional, but the valve guides are quite loose.
I had access to a commercial engine washer (giant dishwasher with a built-in oil skimmer), and put both pairs of heads in it to clean them up.
My old-worn out heads looked fantastic when I took them out. The heads with the good valve guides looked like hell, as the paint had only partially washed off, and was duller looking than the clean metal on the other pair.
So, now I have to get the good heads media blasted before I can use them. I put the bike together with the better looking heads to finish the restore in time for the OVM show in May.
