I have a pair of original Champion cylinder heads for sale. Champion heads were one of the product lines made by Fenton for high-performance use. Check out the photos for a copy of the original ad when they were new. A friend of mine passed away recently and I am helping to clean out his machine shop. This pair of Champion heads were in progress as he had nickel-bronze brazed some material around the top of some of the head bolt holes to fill in some grooves. I machined off the brazing which required carbide tooling because it is so hard. They look to be in good shape to me, but I am not an expert. One of the heads has "020" stamped on the lower surface, which I am guessing means someone took .020" off the sealing surfaces, but I have no reference to measure that. I could cc the chambers if someone knows what the original volume is supposed to be. If you think they are too expensive, just make me an offer.
