FRPP Catalog lists as follows:

GT-40X Aluminum M-6049-X303(64cc) or X305(58) boasts 65HP for $1250
GT-40 Aluminum M-6049-Y303(64cc) boasts 40HP for $1050
or
GT-40 Irons M-6049-P303(60cc) for $538 but doesn't list any HP#

How much HP are the GT-40 Irons supposed to make?

I agree that if you're not concerned with gaining less than 60HP from heads than buy the Irons, but if you did want serious HP from your breathers, than there are probably alot of other heads out there that give the GT-40X's a run for there money. Such as TF Twisted wedge or Holley Systemax Heads.
