Have you been in touch with Hammer? They are excellent technicians and are very helpful...

Hi Samson4651$, welcome to the Forum.

You started your thread in the 'Forum FAQ / How To' section, which is for posts about the Forum, and how to use the forum functions, so I've moved it to the 'Sportster General Discussion and Problems ' section.

Your lifters are suspect if the "wrong" gasket kept them from getting oil.

Did you relube the cams, etc. with a lubriplate or something when you replaced the gasket?

Did you relieve pressure on the cams when you removed the cam cover?

How loud the knock, if very loud, check cams placement, if only a tick, your rocker shafts. They are simple engine.

If you have the wrong cover gasket, one of the oil galleries could have been blocked, starving whatever it feeds of oil. Not good.

A mechanics stethoscope are cheap and will help you pin where the knock is coming from.
