race gas or pump?

[ryskie22]

i have had mixed input on fuel and on how to check the compression, i have 19cc domes in a prodesign cool head on a 350 with a hotrod crank, advanced 4 degrees, 33 keihn pwk carbs jetted at 165 mains and 48 pilots, also the tops of the jugs were surfaced due to imprefections, now my queston is that should i be running straight 110 or 50/50 mix with pump or straight pump gas? ive checked compression many different ways, i really dont know what the proper way is but here it goes, i first kicked the shit out of it and it never got over 155,now if i check one cylinder while the other is running it has 180 to185 idleing of course, and the cylinders are even and this is a fresh topend. so what is the proper way is it that i cant kick it fast enough? from the info ive found this should have 180, oh and i am at sea leval to 500 feet, thanks for everyones help on this its been a question ive had for a long time.
