Alright, Currently Running 180-190lbs of compression little bit of motor work done after a rebuild with a water box added. I run about 50-1 mix with 93 octane pump fuel. I just picked up a Westcoast head that has pump domes on it, or that the dude states. Over stock compression the guy was running 170lbs roughly. Curious to know if this would put me into race fuel at around 100-105 octane. Any help would be greatly appreciated.

You're probably ok with pump gas. 190 lbs is usually considered the ceiling for safe operation with pump gas. I try to stay around 185 just to be safe.
