The smaller engines typcially have a bit higher compression than larger engines with lower compression ratios. I suspect about 150 lbs/in per cylinder with no more than 10 lbs/in difference between cylinders. Hopefully a 550 owner with a manual will chime in. Check compression with the engine warm, throttle held open and all plugs removed.
