Default What could cause this?

Got a call from the guy working on the Vette. He has it on the dyno, he said that after a few pulls on the dyno that the valves are getting noisy. Sounds like that they loosen up. Is that normal? I have a Jesel Shaft Rocker setup. The shaft assembly was removed back in January to change to the bushed lifters, new length pushrods were needed, went from a 6.8 to 8.6 inch, rocker arm alignment was checked. The changed was performed by a mechanic that is a serious racer. It has no run time on the motor after he adjusted the lash and drove out of the shop.

Thanks for your assistance

IDK if it was just put together. Wear in? Lock nuts not tight. I would run or drive 20-30 minutes see if tapping returns.

Did that, did a few more pulls on the dyno, no problems. Will drive it in about 2 weeks.
