62 heads are nice heads.big valve(2.11-1.77)screw in stud,nice chamber,but it is a smaller chamber advertised about 72 i believe but most are found alittle bigger 75/78.even at the bigger size they would give a pretty high compression on a 455 if you don't run dished pistons.if you are looking for a strip set up where you would use race gas,not so much of a problem.
they can be found between 100-250 a set that need redone and up depending what has been done to them.
