This is a really tough one to call your blazing a trail I have not seen a dynosheet for.  In a 103 with raised port head and a 103 properly tuned the cam / motor combo from Kury was making 126/119 give or take a couple on the hp side.

In this case with a 110 I havent really seen anyone use this cam, so it is an unknown to me.   The porting / polishing there is no numbers for or information about what was done.   You say 10.5 to 1 compression, but while it is a number there is other data.    Flows, valvesizes, CC of head etc.

I would hope you get at least 1.15 to 1.20 on the numbers.   If you had used the 24d I would expect somewhere in the neighborhood of 115-122/118-124 based on good porting/valve job, velocity of the head etc.

In a 113" I made 126hp/121tq with the 46G, heads did not have a raised port. Supertrapp 2X1, compression set at 10.6:1 & 55mm throttle body. I also ran a 46G in a 95" with a Thunderheader, more bottom with a Supertrapp, but with a good tune it will still run good with the TH.

Not sure what intake to exhaust ratio his heads are. 75-80 % is good with those cams. Either way, I don't worry about numbers. Those cams have a linear power band, and get you upstairs before you feel it.
