Cylinder head sensor and MAP MS3

A week ago

So I've brought home my Rebello built 3.0 stroker motor and mounted it on the stand. I'm at the stage of selecting and installing sensors. I'm pretty much going with the GM style sensors sold through DIYAutotune but I've got a couple questions you guys may be able to clear up for me.
First, I'm using a E31 head that has been modified with big valves, P&P, and injector notches. The E31 never had a cylinder head sensor so I can't just put a compatible one in its place. I probably should have had Rebello drill and tap for one but that's what I get for planning as I go instead of following a well developed plan. Can you guys think of a solution? What have you done? Or have you done without?
Second, I'd like to have altitude compensation as I live at 4500' and regularly travel up to 9000' (I live off Mt. Rose Hwy) and down to sea level. I know at least one friend who used a second MAP sensor to sample for barometric pressure. I've also heard of MAP sensors that are monitoring both. What are your experiences? What have you done successfully?

Throttle Position Sensor

I just discovered that I have a new '78 280Z TPS sitting on the shelf. I plan on using aTWM "Big Throat" throttle body. I'm wondering if the TPS is compatible with Megasquirt 3?
