Default question about Jessle rocker arms

Just got the 427 running and the valve train is pretty loud. The motor has Jessle adjustable rocker arms. My question is are they supposed to be louder then stock rockers?

They are louder than stock.
Look under valvecovers for witness marks from cover to rocker interference, its a common problem.

I have katech valve covers and they were hitting at first. I had to take them off and grind em down a little bit. I let it run for a while and took them back off and they are no longer hitting the valve covers.
