[J and M Machine]

These are the kind of hard stories that makes all shops look bad.
I had posted long while back about questions to ask a machine shop before handing over your engine.

Clearly if the valve seats don't look right they aren't. If you got them to move then they will come out. Yes: There is a tool that will pull them straight out. Not all machine shops have it though. You can't reuse the same seat.

Interesting part of all this is that you're willing to go back there and have it done again.
If they goofed the first time and had devil may care attitude"good enough" is never good on anything. What do you expect on getting a second time?
If they were so shoddy to paint over the grease that would cut it with me for sure.

You're not the first as we've heard your story alot over the ears we've been doing engines.
If anyone reads my post I suggest you do your diligence and see what kind of work machine shop does, what they are going to do for the money and in this case have they worked on Model A before and was it successful?
