For sale or trade! This is a nice pair of original high compression cylinder heads for the early 21 stud flathead engine. These will fit the -37 early -38 engines with waterpumps in the block. They looks fine with no cracks or major damages, no broken fins. I asking $1500. Trades are welcome. I am intrested in all rare and early speed equipment for 32-48 flatheads. I especially looking for early intakes, other 21 stud heads. Cyclone and Tattersfield 24 stud heads. I am NOT intrested in common offenhauser, late edelbrock stuff, repro and 8BA. Can bring the heads to portland swapmeet, otherwise buyer pays shipping.
