Rover Conversions

Rover Conversion to Chevrolet Valve Covers

Once the standard rocker covers are removed, plug the holes shown in the photo (1) below with clean rags to prevent foreign bodies falling into the lifter valley. You don’t want to have to remove the carburettor and inlet manifold just to retrieve a piece of old gasket do you?

Clean the gasket surfaces up and trial fit our adapter plates. Two of the black countersunk retaining screws need to be relieved to clear the tapped holes used to secure the Chevrolet valve covers. Tighten the plate down and use a felt tip or scriber to mark the screw (2):

I use a Dremel or a file to cut the notch. Remove the plate and lay down a bead of silicon sealer (3):

You can now permanently bolt on the adapter plate. Now add a gasket, either the standard cork or our reusable silicon rubber gaskets (4)

If you are using our stainless steel cap screws they need to be trimmed to length (5). Screw them in till they bottom out and measure the gap between the cover and the bottom of the head. Cut to this length, adding the washers will provide clearance.
DON’T FORGET TO REMOVE THE RAGS before you bolt the valve covers down for the last time.

These instructions can be use for guidance on the Rover to Ford conversion but there will be no need to relieve the counter sunk adapter plate screws as the spacing is different.

Below is a photo showing details for shortening the valve cover hold down screw. This needs to be checked for which ever fastener you decide to use. If the fastener is allowed to bottom out the gasket will not be compressed sufficiently to prevent oil leaks.
