i have a 88 supra turbo and haveing issues with it sounds like its got a dead cylinder but it dosen't. It has low compression in cylinders 2,3,4,6 but 1 and 5 have 0psi. The bottom end is fine i ran it with my backup head while i had my orignal head redone for drag racing i did the comp cams spring upgrade i dont think the valve shims are not adjusted right and if so how do i adjust them

If you didn't touch the valve adjustments, then its possible you need smaller shims and they're constantly holding your valves open currently. The process is in the TSRM for adjusting them.
