VTC/VVL conversion

even if you can convert a notchtop head into a vvl/vtc head don't you lose the flow and head design benefits of a p11 and p12 head anyway? Guess I'd have to do some more reading on why this is a thing.

You?re actually converting the P11/12 head/cam to a VCT compliant setup. Still have the benefits of the P11/12 flow, but increase low end response and trq.
