Wow man, that sucks so bad, I wouldn't expect that from such a high caliber product as AFR. It's also sad because I don't know of many other head manufacturers that make such good heads as AFR, compared with flow numbers and the massive 76cc combustion chamber size available.
Anywho, if you really don't want to use those heads, I might consider taking them off your hands for the same price you paid if they're the right ones i need and if you wish to purchase new ones. 220 cc intake cnc ported? 76 cc combustion chamber? I don't mind the look of my heads up front, i might even be painting them black to match the engine anywho

anyways, give a hollar! i'd more than love to help you out here
