Do it ... I'm not familiar with either 'Gerolamy heads' or '9fg' cams ....
I was skeptical of the old saw 'no replacement for displacement' for quite a while ... finally succumbed ... if 95" is good, 98" should be that much better ....

With Twin-50mm S&S t/bodys, 98", and our Stage III Heads, Wood TW-9FG's, we've seen 123/123. see www.joescyclerepair.com.
That was years ago.

Twin 50's on a 98"? I would think one would be enough, especially on the street? Maybe step up to a 54 for some really good flowing heads.

Yes, Twin 50mm t/body set-up from S&S, with seperate runners.
They actually don't flow big numbers, as they carry an OE intake port diameter of approx. 1.640",(not our choice, but client already had them) as to the design of the manifolds, but they do produce big torque down low.
The American Irom Magazine 98" build(should see that on news stands any day now) went off at 122 hp, and 114 ft/lbs, Wood 9B, with a HPI 51mm t/body,(perhaps it could have made use of a 55) 1.800" intake port diameter, and a Supertrapp 2/1.

I did the GMR Power Pack 2 a couple of years ago. I had issues with the Revolution Performance cylinders and went to stock cylinders bored to 98". Cam is R&R Cycles 615/585. My sig gives the details.
The bike runs like a champ and pulls like a freight train. Roll ons from 40 or 50mph put a big smile on my face. I'm running the stock TB at the moment and just wish I had the cash to do the 50mm TB right now.
