No Banging, or milky oil, and no metal shavings when i drained it! I was told that the rod bearing were probally scorched so that why i am leaning towards just building it while i have it out!! JUST LOOKING FOR SOME ADVICE, but if i do decide to build it i want to throw that xp cam in there, what else should i do along with that! And the new heads are ported and polished stock! Is that compatable?
