For what it's worth, when I had my head redone with hardened seats and new
valves to be an unleaded head, the valves sounded much louder than before.
No amount of regapping changed the tappet sound. However, I'm happy to
report, this quieted back down after 500 miles or so.
For the record I have standard (non roller) rockers, NorthWest Imports hot
street cam and a lead free head.
Good luck,
Robert Weeks
