Myself, I would run the camel hump heads & a slightly dished piston, have the seats replaced w/hardened. Gasket match everything. Use a cam around 290 adv. duration & around .450 lift. Good q-jet or 600 Holley on alum intake. Pay for balancing, get a good flywheel. HEI, double roller timing chain. Not positive you will get 300 honest HP to the rear tire(it is "only" a 283), but this combo has run very well for me on a couple Chevs in the past. I have also seen rodders bore 283 .120 or more for extra cubes. I have my eye on a 62 283 in a C50 nearby. My 2 cents, Brian
