Also an adjustable pushrod collapsing and or a bent valve. those are the only three that would really cause that large of a gap.. As suggested work from the cam chest up.. if no evidence there then bring cylinder up to TDC and put a little air to the cylinder a bent valve will be very noticeable..

Thanks, pulled rocker assembly, pushrod straight. Pulled four bolt on lifer cap to pull lifter but cantc remove.

Did you mean 0.165 or a little under 3/16" for the world or a stack of three quarters (money..ha)

Indicates failed lifter roller which also means cam lobe is probably damaged. Pull the cam plate/cams and the lifter should drop out from the bottom of the bore.
