rnr=remove and replace
todays oil does not have zinc and cams get wiped out real quick. That is why I asked if you primed the oil system. Do you understand what primed system means? (not picking on you, just seems this is confusing you.) You need alot of zinc in the oil, form of additives or some kind of diesel oil with zinc in it. He means you are gonna have to remove your intake and put more break in lube in the lobes. Also make sure you are actually getting those 800 amps cold cranking to the starter.
Can you find some one in your area that knows about breaking new motors, it sure would help and save a lot of anguish and money.Good Luck keep us informed as to how it goes.
