I have a set of old Canfield 17 degree 192cc heads. They are worth good money. I've been offered $1200 for them used off the car. They aren't any better than some of the new heads out there, but people are nostalgic about them. The Twisted Wedge 185cc heads flow just as well. For a short time Canfield was making 22 degree heads to compete in the entry level market. Those are either 170cc and 195cc, something like that. The company lost connection with their target market when they started making 22 degree heads, and that's why they went out of business. I don't think they sold many of those before they went out of business though. The casting number will tell you for sure though. You should be able to google it pretty easily.
