I have a 96 ws6 with LE2 heads, XE 233 cam what should the compression be on this setup. One crank (revolution) gets me 160-170 and 5 gets me 190-195 PSI? Making sure my bottom end is sound?

 

Sounds real good on the 5 times. Ya should just go 4 times and it don't matter if the TB is closed or not.
Do all cyls and see how much difference between them. 15-25# would be good 0 would be better,but that ain't happening.
It's the spread that counts unless ya are measuring for valve timing.
