Default octane for 90 jag

im helping my buddy fix his sled up for winter and we did a compression test on it and both cylinders have 145lb compression. we were speechless.

its s a 1990 440 jag afs

is this thing suppose to have that much compression??

when i did the compression test, the exhaust was off and i held the throttle wide open

and what octane should we run in it?

thanks
