Hey Merlin,
I'm not an exoert but I have had clearance problems when I installed thr Comp Cams 1:85-1 High lift adjustable rocker arms.I had to remove the windage trays and grind a little off the reinforcing web casting on the drivers side.I thought to myself that a taller set of covers would be the answer,just a question of mounting the coil-packs and longer wires.Don't forget to check out the PCV connection locations.
