Heads for '63 75hp

[yorab]

I'm looking around for NOS cylinder heads for my 1963 75hp starflite model 75383E. The original part #s are 307711 and 307263. Found other heads for early to mid-1960's models up for auction, but the part numbers are different. Does anybody know if other heads from the mid-60's V4's will fit on my engine? I'm thinking that maybe some small design changes could have been made to the heads over the years, thereby changing the part number, but they could still mate up with the block. Thanks.

The heads have to be from a 75. 60hp heads will not work as the 60 was a smaller bore. I might have a set from a 75hp Johnson. Will look if interested...
