The only time on this motor was just 25 minutes worth of running to break in cam. I paid over 200 for them and hoping that can get some of my money back, so loss is your gain.
I went with a different set up and decided to go aluminum heads pistons, so had just purchased these head Gaskets unfortunately can not use them the new. Again, these have about 25 minutes of run time on them and there is absolutely nothing wrong with them, unfortunately because they were installed, I to list as used.
