shows none of the cast iron heads sold...although before they redid their website...there were a few sets sold....

Plus there are several other companies selling the Pro Comp heads on ebay ...as said by MadDart,
the Airwolf 220 heads are based on the ProComp heads....as they say...pick your parts and spend your money....
