Johnson 2110R Lifter Preload?
Johnson 2110R Lifter Preload? Hey all, after searching and searching, I can't come up with the recommended preload for the 2110R dog bone lifters:

I'm thinking .025- .030 like the Morels, but I wanted to double check.
Also, if you are using the Johnson 2110R's, I'd be interested to hear your combo and what length you came up with.

When I set up a valvetrain, I measure pushrod lengths for every valve regardless if it's a short travel or full travel lifter. This allows me to achieve the exact preload I'm shooting for on all 16 lifters. Overkill? Maybe. But it's peace of mind for me and I've had great results. The engines I set-up with 2110's get .035" preload. This will account for thermal expansion and still keep things quiet. I've mentioned this before on here...I'm not a fan of deep preloads in search for a "quieter" valvetrain. When things get excited, you don't want that extra preload causing clearance issues with valves and pistons.
I typically tell people with 2110's to set preload @ .040" +/- .010". The same goes for the 2110R that has .045" less travel than the standard 2110's.

Good info.
I measured all 16 on my ride. All were within .006-.008 of each other and my Manton pushrods were all within about .004 of each other. So I just tried to match them best as I could since I ordered them all around the same length. But I felt good knowing they were all basically within .010" of each other.

I had an avg .034" preload for them cold. They only have .052" of total travel. But with the aluminum head and engine, I actually gain something close to .006 or so as it heats up.
