Another cam degree question

-
Do I set lash tight (to zero) for purposes of degreeing then cam? (when dealing with a mechanical cam, that is)
but I bought that proform tool, (dial indicator) that sets right on the cam in place of a lifter. and I still have the head off. so I guess that original question no longer matters/// but the answer might help "somebody else" that might happen on this thread.

and Rusty.... you aren't the one that turned this thread sideways, it wasn't "your bad".
In fact you answered my original Q, in post #2 above!
 
It doesn't make a damn bit of difference what lash You set it to, the only thing that matters is to pick the precisely same mid-lift point on the way up, & on the way down. If You've found true TDC & zeroed the wheel, accurate readings recorded from the wheel are all You need. If You can centerline the cam in one engine, You can centerline any engine. A reliably consistant setup to accurately transfer the profile to linear motion for the indicator will make life easier...there are multiple ways, pick one & go with it.
 
OK if you have the head off you have no lash to set.

Use your proform tool right off the cam and read from there. Remember now you are measuring cam lobe lift and not valve lift.

You can take your cam lobe lift and multiply by 1.5, this will equal your total valve lift with the 1.5 rockers.

The duration is the amount of degrees the valves are open, so you can measure that right off the cam too.
