Are the heads pretty much interchangeable since they are both SOHC vtec heads? Im wondering if the d15 might have like smaller valves (which would be a loss of performance over my d16 head) Basically, I would like my d15 as fuel efficent and my d16 power/fast. But i guess im asking if the head is basically the same w/ the same flow. I would rather just swap the head so i wouldnt have to mess with valve springs and such.
This make any sense?
