Download the cam spec card from Crane, and just use their recommendation for valve lash settings.

Typically we are seeing lash around .35 intake and .45 exhaust for large lift and duration street cams, but those are quite a bit bigger then the stock minimum. This is something I've always wondered about as I would like to close up the lash to something more like .20-.25 intake and .30-.35 exhaust, comments?

If the cam makers don't give you a setting then the standard clearance should be used.
You can play about with the clearance, big clearance give more low rev torque while a tight clearance give good high revs torque.
The tighter the clearance the easier it is to burn out a valve, motor bikes run as little as 2 thou and they don't burn out in a hurry.

Rather not embarrass myself with my gap in knowledge...
Something I was wondering was a recommendation for one to be tighter- I forget if it Intake or Exhaust though.
A little knowledge can be dangerous.

If a person was running say a Schrick 276 that lash setting would give you almost equal to a Schrick 280 assym. The 280 is supposed to ahve better mid range and no loss in top end by restricting the exhaust.
