He he he, post isn't to big. The one parragroh is a little hard to read. (For me that is. No biggie.)

Could you help me out here a second. Just tell me the weight of the car and tire size. (Ex; 235/70/15)

The big block heads of the early years are not really all to different from each other from what I remember. The biggest changes the factory did were to the ports and valve size. Being your looking for about 1.1 horse power per cube, cam choice is alittle tuff considering the 3.23 rear you want to keep.

I think you can use your stock heads with porting.
