I'm very impressed/excited. Three summer ka24et projects all within the NY area.
When I removed the head it was DIRTY. I did what I could with a tooth brush and ajax scrubbing podwer to get things cleaned up. Then after i had disassembled the head, I soaked it in Simple Green and water in a bucket, then scrubbed it down again. That was pretty much it, after that it was very clean. The Simple Green does a great job, you can find it in the cleaning section of Home Depot.
I do keep the rockers mildly oiled to prevent any scuffing when the parts rub on each other. I have two sets all packed away in plastic bags. When I'm ready to reassemble everything I'll go ahead and re-use the old parts. Since I have two sets, if i ecounter any problems in the future it's just a simple matter of swapping the parts. As long as they're in good condition you might as well re-use them, gives you extra money to spend elsewhere.
The head flange I bought from
http://www.jgstools.com/turbo. You can buy unfinished log manifolds from them. I just bought the head flange so I can make my own turbo manifold. If you plan to make your own manifold, buy the flange from them, it's VERY nice. The T3 flange w/collector I bought from e-bay.
