Well got it all back together and runs like crap.I know I set the timing correctly I was very maticulous about it! Won't even stay running at all. put a scanner on it code is "Camshaft Position Sensor 'A' Circuit High Input Bank 2". So I swaped the one from bank 2 to bank 1 to see if the problem would follow. No such luck,scanner still says the problem is in bank 2. Could both cmp be defective? Could it be the ECM ? Going to salvage yard on Saturday,they are having all you can carry for $40. I am going to pull both complete heads and the ECM . Does anyone know the location of the ECM? Is there anything else I should pull while I'm there?
