Actually, if you used assembly lube ( that thick sticky red stuff that comp cams sells) it will take a long time to get it al pushed thru the pushrods to the valves----take out the lifters for number two cyl and see if you have good flow in the oil galley

We had a customer that filled his pushrods with goo and we took them all out and cleaned them and just used 5w30 and he had good flow immediately
