I think (and hope) you're probably right.  I started with the lifters
at 1/2 turn on original assembly and tightened them to 1.5 turns
after the 20 minute run in.  I think the combination of the higher
cam, and higher pressure oil pump  must be affecting the valves
closing correctly.  Resetting the valve adjustment is next .  Wish me
luck!
