Got it,turned out the valve were too tight you can't go that 1 hole turn on the vortec heads like the fsm said its a 1/4 turn after they start to tap still getting that dredded p1345 dtc yes I know what it means but I"ll check the timing again but I'm pritty sure its dead on. I'm thinking the gear on the cam is just worn down since chevys are know for this after so many miles and like a dummy I didn't replace it like I should of but what can you do but to tear apart the fron end and do it. Thanks for your guys input on the situation. The way these past couple months have gone I'm suprised I can still put my pants on the right way.
