^^ Listen to the part changer.

I would do a uccr and a squish test too, 'cause something is off.

Something is off if it's a true 21cc dome with that high of compression.  

I asked ghe guy before me and he said is a high compression cool head

It's not a race motor, I would think 150/160# would be plenty for you. If you want to run less expensive fuel, just get a new set of domes that will work for your setup. 

It has a high compression cool head on it. Im ok with running race gas, I just want to know if I dont have another option, can i run 91? And the engine isnt completely broken in yet

I'm juzt a dumbass oryguniun.  But why would you want 182# compression on this motor. I'd think swapping to lower compression domes be a decent idear

What size would be best. The engine only has 2 hours on full rebuild

I run 91 ethanol free gas w/ 20cc domes at 1100 ft. And have for years.

But I don't have anywhere near 182 compression.

Ok, thanks. Mines a pretty fresh build
