Budget racers quickest stock piston and head motors

The light is set a 5800 seams to have gotten my best times shifting around there. Unfortunately I only have 2 other 600 carbs on hand. Only have one more race I'm going to attend this year. This winter unless I fall into some money I'll degree the cam and thinking about milling the heads .060 and smoothing out the runners and running rocker shims from Mancini. Was also planning on picking up a 6al box and blaster coil and edelbrock performer rpm manifold if I find one for cheap. Oh and probably take it in to get aligned before next race
