I'm just not familiar with a rocker with out a lock nut.
These did come from Rocker Arms Unlimited so thats what the deal is.
On to new push rods.
Thanks for your knowledge and time.
I'm not knocking John's suggestion at all. It's a good one, but IMO you don't really need a checking pushrod. I would simply mic one of the locknuts, measure the total length of one of the 225 pushrods and add the lucknut thickness to it.That will get pushrods that will be just right and you'll be using what you have, instead of buying something extra. Make sure to tell whomever you deal with that you are using the TOTAL length and not measuring down into the pushrod cup. That way you'll be on the same page and use the same measurement.
