The GT heads are drilled for the exhaust bolt pattern to be bolted up at an angle. I think they have 4 holes drilled in each exhaust port opening. They are no better than the run of the mill 390 head. They are set up that way so they can be used in the tighter engine bays.

390 cylinder heads are VERY poor flowing and performing heads.

They are just a standard run of the mill 352, 360, 390 head. The only difference between them and a GT head is the exhaust bolt pattern.
