I have one of your heads in the machine shop right now being re-done, they have everything done now except they don't know what valve stem seals to use. Apparently the stock seals do not work w/ the brass(bronze?) valve guides you have installed. Can you tell me what seals to use, or send me a set?
And to answer the inevitable questions
I am working on Bozo's car (Tony Q), he purchased the head, not me. The head is being re-done because several thousand miles ago the engine was overheated rather severely, was starting to smoke a bit, then blew the head gasket while trying to set-up the air-to-water IC setup and tune the computer. The heat tab on the head was melted, and therefore I did not feel it was fair to ask you to warranty it, and it was (supposedly) quicker and cheaper to just have a local shop go over it than have it shipped back to you for the same thing and then shipped again.
The smoke turned out to be #1 and #4 pistons being galled, apparently from overheating. So this is NOT an attempt to fault your head in any way. Just need to get it back together asap, as the car has been down since Sept, and both me and Tony are ready to see it move again
I think he has put a total of 5k miles on the car maybe in 2-3 yrs, I'm ready to see him actually enjoy it for a change.
