shorter, hardened pushrods?

this may be a little late to ask but should I get hardened pushrods. My heads are milled .030, but the last car they were on used a stock length pushrod. Would I be better of getting a shorter pushrod? If so, how short? Cam is a 224/230 .567/.573 112 LSA on XE-R lobe.

hopefully it does.
