I get about 9.42:1 assuming that the SRS is the -4 cc version. I have run much higher on pump gas, mos I build to 11:1 but I am doing custom cams for ths motors so I can control it somewhat.
I used a DSS Racing 347 block, rotating kit from Coast HP, sent to local shop for balance and piston to bore sizing, then assembled myself. I did set the ring gap on the tighter end of the allowance.
Heads where cleaned up but I cc'd them at 71 cc when done. Not sure what the deck hight was.

The ring end gap is still within Hastings specs. What are you thinking on lifter preload? I have built about 20 engines but I am ready to drop this one off at Walker Racing for a second opinion.

I suggest you check your lifter pre-load. You may find you don't have any.
A loose rocker will not open on time and close too soon... thus increasing your cranking compression.
