I'm not sure the small lobes would clear everything anyway, but the frontmost journals (closest to the cam gears) are configured differently on the VE... so nope.

I stole the VE cam pic from a classified ad (thanks):

Please post the info you have on how RR cams benefit a old school DE for cheap HP. i like to see the gains on a dyno sheet if avaliable .

With what?

There's more to the VE/DE swap than just the lobes. It won't be useable bolting them in. Check the thrust journals.

From what I have heard, the RR SR20/Cams are much smoother on the lobes, which is why you can't run non-RR cams without swapping the head. Hence the Roller Rocker.

I wish I knew more as to why the RR doesn't rev as high safely when stock. There are JWT vavle springs that allow the RR to run to 7500rpm.
