There are many variables to take into consideration.

If you degree the cam with no valve train load, you have to compensate the P/V because the cam will retard 2 to 4 degrees when you start up the engine and the reason for running a tighter piston to valve clearance on the intake side. I like to run a tighter clearance on the intake side than on the exhaust side. Also, take into consideration the camshaft profile and lifter type you are running for valve spring pressure. In some profiles, you do not need high spring pressures.
