Just Blew 2 Head Gaskets at Once. First Run

The way I see it is .015 isn't going to make much difference in compression. I am sure if done right and no pinging ever happens a steel shim gasket will work a very long time. They were used in new motors long ago. But since I don't enjoy pulling the heads off I went with those Mr Gaskets.

Be sure the thread holes are clean and use some lube on the bolt threads so they torque down right.
