I was going to run j heads but the machine shop cut into water when they were putting seats in long story.....that would of been at 10:1 with the kb107 and a 68cc combustion chamber according to the kb book any way I decided after doing the porting and having the head ruined I would go with aluminum heads picked edelbrock heads 63cc with 2.02/1.60 valves and performer rpm intake dougs headers the block is bored 40 over and zero decked. I had also picked a xe274hr cam but with the smaller combustion chamber I was steered into the bigger cam for some bleed off. I agree a bigger cam is not always better.
