What do you consider as being "better" results?

Power wise, I will always try and lash loop any engine on the dyno. I've seen HP gains reducing it, and sometimes increasing it. Every engine was different.

A friend in the late 90's used to run up to 0.040-0.042" on his Comp Eliminator small block. Was hard on the valve train, but it was the nature of the beast back then.
