283. 283!! (and might just consider having a machine shop take care of hardened valve seats so you can use the original heads also - although the 305 route is another route I hadn't considered, as was mentioned above). At the very least, it's worth having a reputable shop actually test the hardness beforehand - I've had a shop tell my mine had a Rw number that meant I did not need hardened seats - and I never had a problem using unleaded in that motor.

283!!! Vette valve covers!!! WCFBs or Rochester FI!!! Nothing can look that good. Ok, I may be a little biased.
