Brad,

It was really no big deal.

Wound up using 1pc Race W-2 style 'Billet block' type pedestals and used the 1.6 Hughes Victor intake rockers....took a bit of relieving around the intake port walls to clear the pushrods for my low deck roller cam combo....for a flat tappet RB it would probably cleared without any real work. Rocker geometry worked out really nice.

But the really astounding thing about the 285's is the Chapman CNC work, the beautiful (uniform throughout) port shape and the Flawless Zeus Castings themselves....head and shoulders over anything mopar ever produced before.
