2.02 valves, port matched. Light polishing, 7/16 studs and push rod guide plates. .550 springs, 61 cc. Magged and cc'd. Fresh from the machine shop. Non hardened seats. No acc. holes. Look great, should make mucho horsepressure. $600/pr. Interesting note, one one the heads says it a 461, because the factory failed to change the casting mold number. They both are 100% 462's. :D
