Did try lashing it to. 024" once cold to be lazy as doing a hot lash makes a mess because these heads don't drain very well. Car lost 2 tenths. If anything it likes the lash a bit loose. Cam is currently retarded 4 degrees also. Tried it 2 degrees advanced, hates that too.

a lot depends on the combo. He can try both loose and tight. My deal, a stroked 440, loved tight lash cause IT was way under cammed. If his motor is shifted at a higher rpm with a looser converter, it might love tight lash.
