New cam install ?'s "Help"

[Dark_5.0]

I got rid of the 90LX in favor of the cleanest 90 coupe you have ever seen.

I got my engine sitting in the garage floor and have decided to try and go with a Lunati .536 lift single pattern cam.

Since the heads are already bolted on how do I check for piston to valve clearance?

I was thinking about intsalling the cam and bolting down a few rockers and then gently turning it over by hand.

Is this an acceptable method. BTW speed density is long gone. I now have mass air

Thanks,
