Personally, I don't trust anyone. I will always tear it apart and check all clearances. Nothing against Lonnie. (never met or talked with him) But, I work in the aviation world were everything is supposed to be double/triple checked. We still get $750,000 black boxes that "smoke" on install. Too many things can be overlooked in an engine. But.......If you are not well versed in engine assembly or do not have the proper tools to measure everything, I would still pull the valve covers and verify valve adjustment, and then pour alot of good lube on the rocker arms (stockers) and make sure the valve cover gaskets are glued to the valve cover. Take a flashlite and check the intake end seals to make sure they are sealed tight, re-torque the head gaskets with the valve cover off. (loosen each bolt one at a time and re-torque with a good torque wrench), check intake bolts for proper torque, check cam thrust (roller cam), verifiy crank thrust is with in spec., make sure new freeze plugs were installed, check oil pugs in the back of the block, Verify the oil pan gasket is a cork one, not rubber. Check running torque with a torque wrench to make sure it's not too tight, though it will have considerable drag depending on hone and ring package. 'Bout all I can think about right now. Good luck with your new engine.:smile:
