PCV issue

Rick, I failed to mention that I adjusted the valves while they were cold. I took the stock 273 numbers (.013 and .021) and went .003 less. Do you still think I should loosen them up? Also, I have a PCV valve on the way. Thanks!

I think you adjusted the lash spec .003 the wrong way. All the metal expands when it heats up ( steel more than cast iron ).
