Hello, i am in the process of installing my new Boport head. I ensured the engine was at tdc with a piston stop method and removed everything from there. The instructions say to level the cam with the ebar method with the #1 lobes pointing up. However my existing removed head has these front lobes pointing down. I am confused if i should install the head with the lobes in a different position as to what they were when i removed the old head. Please advise Thank you!

When you originally set the engine to "TDC" it was on the exhaust stroke, not the compression stroke. So it wasn't actually TDC, it was 180 degrees off. If the distributor is still installed, rotate the engine 180 degrees until the piston is at top dead center again (this time with the timing mark also aligned with or very close to the TDC mark on the crank pulley) and then install the head as Bo's instructions say.

Also, after doing the above method, the " 0 degree" mark on my adjustable cam gear isn't exactly straight up and down. Its a small increment to the left, maybe one tooth. Is this a problem?

Is the cam flat according to the e-bar? If so, that is "real" 0 degree and you adjust from there.
Also, for most gears, the 0 degree mark doesn't align with anything other than the gear itself so it's location doesn't really matter. The cam keyway should point down though.
