On the street, I would want a set of 670 heads. with a compression ratio of 9:1.. I would go for as many cubes as you can get. Big cubic inches with 9:1 low compression really works well.. I always had better luck with closed chambered heads. Use a cam like the 068 or even better the Crower solid made for Pontiacs.. Use a iron points distributor with a good set of Accel or Standard points set to 30 degrees dwell. Then pick up a Vertex Z-6 CD box and use the points to trigger it..
