Guys,

Thanks for all the good suggestions. I did ask the owner to pull the valve covers and take a look at all the pushrods to see if they are or have been hitting the intake. He did look and found no problems. The best news of all is this: I asked him if they re-adjusted the rockers after the initial 30 min. run-in on the dyno and he said they did not. Even though this motor has juice lifters I would think you still need to re-set the rockers after break-in. I asked him to get somebody local to come and run the valves, perhaps it is just a loose rocker! (I hope, I hope, I hope)
