Get a good steel crank, should be able to find a used for for about $100-$150. Have it checked and polished. Then a good set of Stage II rods will be the next step, and put the bottom end togther with the ARP Wavelock bolts. ARP has set the standard in bolts, and recommend them to anyone. Worth the extra cost. The heads you have proabably won't flow that well that high. A good set of Dart Iron Eagles or Sportsman II's would be nice. Do a little on the port work,expecially on the exhaust side on the Sportsman's.Cam,look for a larger one with quit a bit of duration,like the Comp XE284 or Comp Magnum line.With the Vic Jr. and a true 2.5" dual exhaust, you should have a great runner. That also will need deep gears and a decent stall to utilize that package.
Good luck and happy building!
