oops
"and 4 30psi:
1 and 4 and flat lined, so lash set wrong or head is warped like banana shape.
or both cylinder have bad valves.
you can set the leash , the put a hose in to the intake TB ,under butterfly plate or at vacuum booster port nipple,, and other end to ear.
turn crank slowly and hear all 8 intakes valves, at once, no hissing. our gushing.
the exhaust ports can do be done like that, too, one at a time, (make sure lash is right first, so as not to find bad lash hard way) that is ,same hose in ear.
once sure valves leak , its inspect head time.
but ..
( if rings are bad the oil test trick during compression test , causes compression to rise real fast proving it so.) but not from 0, sorry. that is bad breach.
all these comments assume a real intake stroke happens and full compression stroke, and that he cam is not timing backwards.
