Crazy, I took my Stealths to the machine shop to have better locks put on and check them over.

They checked out fine. The machinist was very impressed with them. He said these were by far the nicest set of heads in this price range he has seen. He had a set of Chevy heads he was working on and one them had terrible core shift and he had a lot of time in them.

I cannot give any real world experience yet.

Thanks all,
