The vvel is different on each head for the same reason one appears to have more lift than the other. But is actually the same at the valve. Also @ MA Motorsports whats up ray?(unsure who's managing forum duty) i spoke with you a few years ago at the FD of long beach when the shiz happened with essa. Had a bunch of life crap happen. Im working on a new vk56 project will call the shop next week.

Spot on, and this is Daelen but I will get the message over to Ray! Holler if you need any VK info, we are always working on some fun stuff with those.

Jim wolf is very aware of the situation and this was taken into account. The OE measured the lift from the "base circle" of the cam, and JWT based the design off that also. So the lift/duration does not vary from side to side but the base circle will, the same as the OE. All due to the VVEL system and how Nissan set up the heads.
