differance between mach 1 and cobra heads

Is their any differance between the mach 1 and cobra cylinder heads? With the correct intake for each application which would be an easier four valve swap for a gt? Im sure they have differant cam profiles but how comparable is the flow? This is out of 99, 01 cobra mach and terminator heads.

The Mach 1 heads are the same as the 03/04 Cobra heads. Unless you plan on swapping an ENTIRE 4V motor just forget about throwing some 4V heads on your block.
