I'm looking for some standard push rods for my Gen VI 502. Merc part numbers and lengths are as follows:

Intake (part # 852003) 7.67"
Exhaust (part # 852004) 8.63"

I measured my old push rods and the lengths above are correct. When I was looking for the gm performance parts equivalent I found this part number:

12368081 which is the kit for all 454 and 502 crate engines but the lengths listed are not the same:

Intake 7.575"
Exhaust 8.525"

I know there are different ways of measuring the push rods which may explain the difference but are these the correct push rods or do I have to order directly from merc?

Thanks!

Let me look tomorrow, I had two sets of brand new take outs.
I know I have one cam, with springs and retainers left if you need a cam.

Yes, Gen VI roller cam. Engine is currently being rebuilt, heads haven't been milled.

Yes, the GM Performance pushrod number listed above are the correct length. Got them yesterday and measured them up. Hope this helps someone else.
