When the top ends get overheated then the valve seats warp and you have
lower compression and the engines flood out. I do not quite understand what
your readings mean as most gauges we use are psi. You should have around 150
psi and up after four to five cranks. If they are down around 100 psi then
you have big problems. You will need a valve job for sure and possibly a
compete overhaul depending on cyl leakage. Might be best for you to take it
to a qualified shop for diagnosis.
