Any chance a Magnuson 2300 supercharger meant for a '14 up 6.0l fit a cathedral port 317 head with intake adapter from ict billet?

 

no, not a chance

How are you gonna fuel it?

 

6.0 is port inject, but the heads are rect port. Haven’t seen the adapter plates but they have a tendency to mess with your transient fueling. I suggest just finding the correct one and saving yourself the head ache.

 

Just get the setup for your rigg and save yourself the headache...
