Actually, that will give you a more accurate check of actual valve lift,
which seems 'better' to me. If you do want to measure cam lift, remove the
rocker shaft and put your dial indicator on top of the push rod.

Reputable camshafts are normally rated in valve lift, which includes the
effect of valve lash for solid lifter camshafts.

Yes. I believe most Triumphs used 1.5 ratio arms. And, this ratio should
be factored into the rated valve lift.
