Rocker bolt/stud bottomed out

Ok so when I search this on google I get some wild answers.
Ok so over the past few months I've been painting and rebuilding my 95 mustang. Complete rebuild stock short block, cylinder honed, new rings, bearings, f303 cam, double springs, gt40 heads, new LIFTERS.
Well I went around during rebuild found base circle in firing order, found 0 lash torqued to 1/4 - 1/2 turns on all rockers to get to 18ftlb (was 3am doing this trying to take a sick wedding burnout pic).
Well had a valve noise, took driver valve cover out and found 1 rocker that is loosey goosey, went to find 0 lash again and my rocker bolt is bottoming out right at 0 lash (no up or down movement) but there is no way to torque it down.
Could this be a stuck lifter in the bottom position?

have you checked the bolt hole for effective depth, nothing stuck down there or debris that is preventing the bolt from moving?

Should be able to rotate engine and watch pushrod come up. Then compare pushrod on another cylinder by rotating engine til it is at top. Should be the same height...if not you have lifter problem.
