360 Magnum with 42rh install angle question.

I’ve got the engine and transmission in, but haven’t built a crossmember yet because I’m unsure on what to do about intake and transmission angles. I’m using the stock efi on the 360. I have the chassis level based on the inside the door on the rocker panel. I took angle readings at several different spots for the heck of it. I’ll attach pics of the readings and list them below. All degrees are downward front to back (lower on driveshaft end than crank pulley end)

Top of intake: 2.1
Thermostat area of intake: 2.1
Crank pulley: 3.2
Top of timing cover: 0
On output shaft on trans(on the splines): 1.8
Along top of stock valve covers: 2.1

I’ve read several threads saying the top of the carved intake should be level when chassis is level and that would put the transmission output shaft at about 3 degrees down. I can’t find anyone talking about angles for the stock efi. Any help would be appreciated.
