Would anybody be able to tell me the between the "J" casted cylinder heads on the 455 and the "G" casted heads? is there a rarity to either? perhaps a ballpark price, if known?

G heads are run of the mill 71 455, could be either small or big valve. J heads are 73-76 smoggers, good for doorstops in stock form or can be ported to flow just fine. Both have 80 cc chambers. Neither were used on W-30s, if that's what you were asking.
