difference between the "J" and the "G" heads?...
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.
