once again i'd like to thank all the guys who origanally responded to this thread. unfortunately all of you were off base.. but after all this is a learning experience. since hindsight has 20/20 vision the problemis obvious after reading the thread. any way .... the problem was a defective lifter even though brand new. since it was on an intake valve
it didn't exhibit the carb poping an unopened exhaust valve would but obviously affected engine smoothness.
moral ..take nothing for granted....................
