4.7 question

Hi,

My cousin has a Dodge Ram with the 4.7 v8. Was looking around for performance parts seeing how a lifter took out part of the cylinder head....We found a place called airram.com....Found some nice replacement heads for it, but when trying to get cams (H/0 cams like in the 04 Grand Cherokee, or 206 cams) they say they're out of stock. Do anyone know of any other places? We even called to Crane to see if they will regrind, but no luck, and couldn't get through to Comps.....Any help appreciated....Thanks
