How do you tell

If you have a set of calipers, measure perpendicular to the lobe then parallel to the lobe and subtract to get the lift at the cam...

Then multiply it by 1.5 to get lift at valve...

You can at least get a ball park for the lift of the cam...

For the rest, you will need a dial indicator and degree wheel...


Can you use "V" blocks do you need a block?
