Well... two months later and still no adjustable Rocker Arm Assembly. I phoned Gary at Rocker Arms Unlimited and was informed that the core that was destined to be my rebuilt assembly had been returned to the original owner -- and I was out of luck. No email notification or phone call. Anyone remember when customer service was a thing?

I'm still waiting on my 1.5 ratio adjustable rocker assembly -- going on 3 weeks now. I guess the lesson here is: Inline 6 rebuilds are not for the impatient.

I phoned Gary at Rocker Arms Unlimited. He is waiting on a shipment of bronze bushings for the rebuild of my adjustable rocker arm assembly. They bore out the arms and rebush to match the thickness of the replated shaft. He said if he had a decent adjustable core he could turn it around faster, but unfortunately I have nothing to send since my I6 has a non-adjustable assembly (hence why I am swapping for an adjustable). He suggested if I get impatient I should use the stock non-adjustable assembly, and adjustable push rods. The adjustable push-rods are 2 or 3 times the cost of the ball and cup rods I have in my hand now...

Have you had that happen here?

Matt, Any updates on the rocker assembly? Or should I get on the horn? Greg

Thanks Matt. This is helpful. I ordered last Friday, so it wouldn't be unreasonable to not see it ship until next week. I'll await a shipping notification from rockerarms.com.
