Have bought an LP UB for 5mph. Has 10A1700 crankcase, 10A150A jugs and GE30Z heads. Thought it was original LP config but from what I"ve read, this head is a gas head and not LP. I need help understanding what it is that I have.

Thanks in advance

GE30Z is a gas head. 6.34-1 compression ratio.

this site has a link to all of MMs head data

Nice site.
Do you know of anything like this for Farmalls?

Thanks for the info. So, in a 403 application (6" crank) would this yield the 9.1 compression ratio?

10A4210 10.7 283 6.95:1 140/160 403 9.1:1 175/210 336 8.0:1 150/175

GE30Z 11.3 6.34-1 130-150

Depends on the piston, but it would be close to 9.1-1. The 30Z looks like a little lower compression than the 4210, so if you replaced a 4210 with the 30Z on a 403 engine and left everything else the same, the 30Z would be a little lower than 9.1-1 comp ratio.
