Engine model#?

The excessive clearance could be because of a stuck valve, bent push rod, something stuck under the valve face, rocker arm stud backed out, etc...

valve clearance

valve seat is in place ,valve moves freely and closes fully , is not bent . its not a over head valve motor and the lifters are solid lifters the top lifter may go back firther into motor . but the valve still opens a little with the 1/4 large gap. the motor had low to no compression . thats why i asked the specs of it , well it going to meet a air gun soon and i will inspect the cam inside after i look up the specks. i thought that it was something new for compression releaf . its got to be something with the timing gear and cam lobs.
