I got back to the shop this evening to measure the pushrod length. I have not checked them all yet, but to get a ballpark estimate I measured a couple across the banks. They were pretty consistent at 9.1955 give or take 0.0001". I only measured a couple, so that range may change. I tried to set the adjusters as equally as possible. I snaked my dial indicator tip down on to the lifter cup, and measured preload with one full turn of the adjuster. I think Brent said one turn would do it. It was dead on. I was a little surprised how accurate just eyeballing one turn was. I didn't have any 3/8 machinist gauge balls, so I used a depth gauge to check the cup depth to know exactly how much to subtract from the overall measurement. I think I could probably use 9.200 length pushrods if I can find any.
