Best thing to do is give me a call. The 155 is a taller engine and it may not fit into the frame you have. But there are other options like a 113 that makes 130/130 or a 127 that makes 140/135  now the 139 may fit I would have to re check the height but can you say 160/150 ???  these are power house engines that will run extremely cool on pump gas and as far as comparing it to a stock engine they are not even close, billet crank and rods, custom fly wheels, billet case's ductile cylinders billet heads.  Left side timken bearing ( normal) but on the right side there is a timken and a ball bearing to keep the crank even more stable. These are a work of art.

I have a S&S V111 and a Rivera-Primo 6 speed gear set with a Barnett Scorpion. clutch.
I am very happy with it. No problems at all. Got almost 10k miles on motor so far.
My last project is to replace the 39mm front end with a 49mm and my FXR4 CVO is finnished!

I have several friends running ULTIMA 113's all very happy. Curious about the Ross pistons as I have them in my 96 Wide Glide hooked to Truet & Osborn heavy stroker flywheels about 15k so far and runs great.

ive also used ROSS pistons in other applications and had real good luck with them (ran them in our 149" progas bike for a while),dont think is was a ross problem as much as it was a ULTIMA design problem,the 4.25" bore ultima motors motors were eating ross pistons,got alot of conflicting answers from kenny @ ultima (timing off,pistons were machined with ft & rr being backwards),whole bunch of stuff i wasnt buying,then they made the switch to mahl,no more probs.go figure
