LSA Question

Dan,
You are a thinker & that is good; thinking out the issue & trying to make an informed decision.
A custom grind is a good idea, but sometimes with FT cams, the available cores limit LSA to 107/108.

In my opinion, you are over-thinking IVC. What happens just before IVC? The valve is closing & is open just a few thousandths. The way more hp is made is to hold the intake valve open longer & with more lift; hence roller cams with 0.700"+ lift.
I would NOT use a dual pattern cam if low/midrange tq is the goal. Use a single pattern cam with more intake duration. Such as the Isky 264 Mega which is on 108 LSA.

I was offered my cam in 108 or 110. I did 110.
It was ground with 4 degrees in it. With one chain was perfect when checked. No need to use offset keys or multiple key way gears. Got lucky
Another same cam close in size had to use the multi key chain and gears ground at diff time. All motor have variables everything must be checked to get the most you can out them.
And my very last custom was this solid degred easy with multi key gear set
