bad machinest

[3RD STRIKE]

I had a L28E head reworked and the machinest cut the head to much,he said he did not. I took it to another shop, they said it was cut .30 it seems to be to much. They said i could use it if i could find a spacer. Does any one know where i can find one of these? THE FIRST MACHINEST SAID I DID SOMETHING WRONG. But i know i didnt ,Itried everthing i knew and nothing worked, I checked compression it was way off, I checked the timing it was right on,so ipulled it off put the old head on and it works fine.The second shop said they would not go any more than .15 on the spacer. And also does any one know how much you can mill off of a stock head?

Usually, A machinist will only take a skim cut of .010"-.030" and the cam and such is just reassembled. Unless you are tryinig to raise the compression. More than about .030" and the cam towers are shimmed. If you are talking about .3" (more than 1/4") I don't know if the head is any good or not. I'd think the valves and pistons may interfere. Fortunately heads are easy to come by, but the head may need to be gone through for valves etc.

Can you still read the head number embossed in the casting? If you have lost .3", I think the lower part of the cast numbers will be gone.

Thanks for the input. The head woudn't even hold a vaccum test. I know the valves aren't seating. ITs not a big deal, i was trying to raise the compression i had told the machinest to take off what he could safely. It just ticks me off that i paid someone to do a job and they didn't do it.

If you know anyone that has a boat, i have a great boat anchor CHEAP!!

Thanks
