From all of the posts I've seen in the past there are plenty of people running the z06 cam with the stock length pushrods & stock block w/o problems. On the other hand, the only way to be certain is to use an adjustible pushrod once you are assembled.

To have the same load on the hydraulic lifter you need 7.425" pushrods. A .050" smaller base circle means half of .050" or .025" on the pushrod end. The numbers are 19.7mm for standard ls1 19.3mm on 01 ls6 and 19.0mm on 02 ls6. These are radius numbers or half of the base circle. The size difference on the radius is .7mm or .027". The 02 ls6 valves are .6mm longer to compensate. That is .024"....the closest pushrod would be 7.425"!
Hope that all helps!
