Pushrod Problems?

Careful! Don't "just remove" the locknuts and assume all is well. Normally, when Gary makes that, mod he runs a tap through the rocker and runs the adjusters through a die and removes any self locking function of those threads, so all you have is the locknut that holds the adjusters tight. So inspect that very carefully. If that's the case, you will need longer pushrods. They will need to be longer by however tall those locknuts are. Without the locknuts, those adjusters should be pretty tight. I've never put a torque wrench on them, but I suspect it would take 10-15 LB FT to overcome the self locking feature and turn the adjuster. If they are "much looser" than that, I would get longer pushrods and run the locknuts. IMO, if you're building any kind of performance engine, the locknuts are a good idea anyway.
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.
