open chamber or closed chamber does not affect valve to piston. my guess is wayne did not have 0 deck. do U have shorter than stock pushrods to get LASH with solid cam/lifters and stock rockers???
I would have to compare them. I ordered the pushrods at the exact length that it had previously. Does 8.9" sound right? Been too long. I will have to break open the motor again.
I am going to be changing all of this back to hydraulic with a smaller cam so that I can keep my factory rockers.
