I'm not worried about that anymore. I did do a compression check after it ate the first plug, it was slightly lower but nothing to worry about, however that plug wasn't chewed up either. It also wasn't knocking. When spark plugs are getting chewed up and the motor is knocking, there's no test in the world that's going to give a result I want to see

From what I can tell, any L67 should be a direct bolt in, correct?
