Hey Cylinder heads guys- advice needed

The trouble with moving the stands is that these blocks and shafts are drilled off-center to accommodate the long valves. If new blocks are made with different offset then the bolt holes will no longer line up with the holes in the shafts. I’ve already been down that road. It would be VERY costly to try and move the shafts any direction other than up or down.

Yeah, you can’t move the bolt hole much further than what Chrysler did. With that rocker system you are limited to about 2.100 installed height, and that’s pushing it.

Fortunately, you can now get springs that go in at 2.000 that are better than everything I used at 2.100 and it’s easier to get the geometry in shape at 2.000 than at 2.100.
