Just bought a set of hardened push rods today. They should be here next week.

You have guide plates?

Hardened pushrods are realy only needed with stud mount rockers and guide plates. With that set up the pushrods rub on the guide plates. They are hardened so they don't were out from rubbing on the guide plates. If you have pedestal mount rockers (which you do with the GT40Ps) then the non hardened push rods are fine. You won't gain anything with the hardened push rods. They won't hurt, but unless you need new ones it's a waste of money.

What's wrong with the pushrods that are in the car noiw Vinnie?  Do you think the "sewing machine" issue your engine has compromised them?

Not really....but not really sure. They have been revved over 6000 a few times, and for the price I got the hardened rods, (ha, ha....I said hardened rods.LOL), I figured that It can't hurt anything. Overkill? Probably, but not in a bad way.
