Head swap

Well I picked up a 4.0 head a few weeks back so I can do the 4.0 head swap on my 4.2
Well I checked the #'s and it is the good head from a 93HO cast #7120
Turns out that its the better of the 4.0 heads and flows much better than the other 4.0 heads. So now I am doing so cleaning up on it and porting it mildly. Hope to get it into the maching shop soon to be tanked, milled, water ports welded and checked for cracks.
Here are a few pics

Can anyone tell me if the intake is going to be a problem? I plan to use my carb and I am seeing some info on the net that says the 4.0HO head cant use my carb intake. Can anyone shed some light on this. I am not looking to go FI as of yet if at all on this.
