New cam timing

[Joe Lansing <kidjoevid@yahoo.com>]

I'm an amateur going through the reassembly of my
1275. This week I'm timing the cam, and Kent says:

After having timed in the camshaft check that there is
no valve to piston contact. The minimum clearance
between the piston and the valve should be 1.5mm. In
multi-cam engines ensure there is no valve to valve
contact.

How does one check this?

Thanks,
