Jeff, before I pulled the head I tried your suggestion with the
oil. It made no difference in the compression level.
Poorboy, we pulled the head off this evening. The cylinder walls are perfect. There is about a one-eight inch superficial triangular nich in the top of the piston just to the out side of the dish but it did not even get close to the outer edge of the piston. The valve looked good and there were no visible cracks or signs of a leak. Hopefully, I can get the head to the machine shop Wednesday to be magnifluxed.
If I do not get it fixed, I will put blue flame decals on it and try to sell it to the Bow Tie contengency of this club as an "original Corvette engine." If they would put a Chevy engine in a Cobra there is no telling what they might buy.
Just kidding please do not fillet me with negative posts.
If you do not see the results of the magniflushing in this post in a few days then check the For Sale thread.
