Valve train noise
my 2006 ZO6 engine was rebuild because of the roller lifter surface deteriorated and deposited metal particles throughout the entire engine. a very reputable engine builder did the task. Crank was ground .010” Mahle forged pistons replaced stock units Jessel Y2K shaft mounted rockers were added, Morel hydraulic roller link bar lifters were added new Ferrea stainless steel exhaust valves along with tapered valve springs a Halltech intake system and tri y Pfadt ceramic coated headers along with a mild Comp Cam camshaft finish up the build. Took the car to a tuner to reprogramm the ECU the stock ecu was locked and replaced with a new one from Chevrolet. The “Tuner” claims noisy valve train all clearances were as advised by Morel and double checked.
Does anybody have any experience with this type of set up? Your comments are most welcome

Post a video of the noise if you can. Is it a "noise"...or is it just you feel the valvetrain is noisier that you'd anticipate?
Hard to say what you're hearing at the moment, but maybe lash isn't set correctly?
Also I highly encourage you to PM forum member Michael_D for some advice...extremely knowledgeable and runs a (Crower) shaft mount setup on his LS7.
