It appears I installed them backwards and the steam plugs are now well plugged, can I just drill them out or something cause I don't wanna pull my heads back off?

The heads are interchangeable. You didn't install them backwards.

Why doesn't the coolant crossover thing go in then? the part under the inlet of intake manifold, there is no holes for the coolant ends to go into?

Maybe, but you'll still have to plug the holes that are now on the back side of the engine. If you can't get to those holes to install the plugs, then you're going to have to pull the heads back off anyway

pull the intake, not the heads.

It sounds like the rear plugs are now installed in the front plug location. Quick and easy fix if so. Pull just the intake (with rails and throttle body still attached) and then move the plugs to the rear. Install front cross over tube. Reinstall intake and such. now its done! No need to remove the heads again.

But I would buy new plugs, not worth the gamble of having a coolant leak.

Well I ended up drilling out the fronts, and hooked the stock ones up and I ordered the delete kit for the rears from Texas speed, seemed way cheaper and easier than pulling the heads lol
