I am in the beginning stages of making a new VC for these engines.
Going to keep the oil fill in the front. Make the breather/ fill hole a 1.25 Push in design.
This will also be a 2 Bolt (center) design. No perimeter bolts.

Is there many people that want the perimeter bolt design? If I understand correctly, the center bolt VC can be used on perimeter bolt engines if you add the 2 required studs to the rocker assy.

Does anyone see a need for a Rear PCV? Or just continue to rely on the draft tube?
