If they were decked your squish would be tighter than .055 , can you cc the domes yourself , I use marvel mystery oil and a big medical syryng, static compression and uccr are diffrent tho , if you can calculate uccr with that dome it would give you better idea . I have ran 175 psi on pump but motor was set up for it with help from mull engineering, I would try giving him a call , maybe give him some measurements and see what he says
