Original heads off a running engine. Glass bead blasted. Some fins ground down for an oil filter, some pitting, etc. but over all in great shape. Please see photos. These are the first ones I’ve seen in person, let alone owned, and probably won’t come across another pair. NO CRACKS Make an offer, trades, etc?? I’m looking for a set of Weiand Cheater heads, an Original Slingshot, or NOS Made in Canada heads
