Any difference between Pre-Eco roller rockers?

Hi,

I picked up a set of YT RR's to suit a VP V6 from the group buy a while back, but never got into using them...

Now I'm gearing up for a new project, I was wondering if they'd fit a VN Series 1 V6? (Pre-EV6 in other words)

Cheers.

If they don't fit I've got some from a VN ser.1 streets , non adjustable type. PM me

series 1 have different size rocker bolts from memory

Yep, different bolt size. Can probably use a recoil kit to make them fit though.

series 1 and some vp have 3/8 mounting bolts, vp - vr have 5/16 mountings bolts ( have seen some vr with early size too) may have been change overs???

cant really interchange these, head can be modded but rocker arms need different trunnions (shafts) and mounting hardware.

Cheers
Mike
