Help with finishing a 383 torque monster
Have an assembled 383 (no heads, no cam). Goals are pure chassis twisting torque right off idle and not too concerned with anything too much over 3500. The pistons have a D-shaped dish in them as well as valve reliefs on one side. We *THINK* the pistons have a 16cc dish. My question is what kind of heads will allow for using 87 octane gas? Will the ~65cc 193 swirl ports work for this?

You should be ok, depending on the actual dish and your quench height.

if your heads have been resurfaced for flatness, figure 64cc
