With a single pattern cam at 242 int/exh on a 112 LSA and an ICL at 106, yes torque would come on early in the powerband. And at a 110 ICL, it would be strong 4.5-6k then drop quickly thereafter. I don't know his ICL, and I didn't know his SCR. From what the OP said, he's setting up the motor with stock pistons, gasket, and head chamber size. So 10.25-10.4 ish SCR? BBCs typically use a single pattern with a wide LSA for strong midrange.

On what part of that, adjusting the cam timing or what I said on the cam characteristics based on the theoretical ICL?
Honestly, I don't see a problem with that cam on a 110 ICL whatsoever, I think it would work well. If it were on a 106 ICL however, I see it going from 3.5-5.5 peak to peak and dropping off and I suggest retarding the cam timing to push the powerband higher.

I calculated the compression ratio with mr gasket 5716's and got 11.32 to 1 so i am gonna go that way with the head gaskets, havent found the cam card yet tho

Its not a BBC.

I more than understand an LT1 isn't a BBC (we could only dream it was, lol). I was just saying that because you'll see alot of guys with mild built BBCs running very strong midrange intended cams so they don't have to wind a larger motor to the moon and make the majority of their power in the intended range. And on a 106 ICL 112 LSA, I honestly don't see it peaking way past 5.5k.
That's not what I'm saying at all. I'm saying this particular cam on a 110 ICL and a 112LSA will make strong midrange and peak right around 6k-6.2k, and drop off on this particular combination.
EDIT - I'm not saying the motor wont pull well over 6k, I'm just saying the peak power should be around 6k-6.2.
