Pushrods on a regrind cam???

Fast01 said

A regrind reduces the base circle of the cam, so in theory you should need a longer pushrod. The actual length is not a given that applies to every combination. You must properly measure for correct pushed length. There are too many variables to be able to say you need "x" length pushrods. If your pushrods are shorter there's either a good reason for it or they're incorrect.

I figure that was the case but wanted to be sure. I think the dude had the wrong ones because they had a wear spot like it was rubbing against something. What is the correct way to measure on a magnum with roller rockers? I know the correct way with 273 ductile rockers where you want 1 1/2 threads showing for correct geometry but is that same principle applied on magnums? Thanks for the response.
