Selling 1965 Hipo heads, Dates are 5C18 with No, 19 and 5D28 with No.20. One head had a repair which was done well and checks out on a magnaflux test. These have been ported and machined for 1.94 and 1.45 valves. These are for a higher RPM engine based on porting and valve size. Rocker arms, springs, and valves have been removed and are in a box. One rocker arm is missing. Will have pictures by this weekend.
