It'll work fine and maybe even a little better with the updated combustion chamber design. No mods necessary. If you look on the top rear fin by #3 intake you should see a 392 which will ID that head as a 75/76F or 77K. My K8 head also has 392 but with an added hand stamped K8 next to the 392. This apparently lets us know it has the different keeper/spring system of the F2/F3. You may even get a compression bump too. The later engines had 9.2:1 ratio. It has been said that was due to pistons but I have seen both piston designs in these 9.2:1 engines leading me to think it is possibly due to the hemi design head alone. I'd really believe this theory if we had someone cc both heads.
