440 build questions

The procomps are probably a Victor copy, with those valve sizes. They won't work with your rockers, they need .650 or .800 offset. And like the Eddie Victors, they're complicated.

440 Source, Eddie RPM's or Sidewinder heads are probably the least expensive good options. The TF 240's are all the rage right now, for good reason, but are a decent $ increase. Your $, your call.

The iron heads are viable if they don't require more $ input. If they do, you're ahead saving that money to put toward the other options above. If you can find someone to buy the iron heads from you, for a 'rules' class or resto, even better. S/F....Ken M
