Yes I do. When I was checking piston to valve clearance compared my adj. pushrod against pushrods provided by Rocker Arms Unlimited. Why they provided them do not know but very close to my needs. Do not know the actual effective length at this time. That determination is pending getting the heads on. It's just like many of these suppliers to stipulate consult your service manual for torque specs. The exception so far for me is ARP. Even if the bolts from Hughes are grade 8 vs. stock 5, required torque would be the same would it not.
