Deeper dish pistons.
When you put the rover cover on it helps to drill the 2 oil drain holes in the block from the valley cover chamber to the timming case chamber.
Does anyone know where to get oil filter/oil cooler adapter for the rangie timming cover?

News to me ive done a few 4.4 coversions and as well ive seen a few done and not one has had the holes drilled from the valley cover to timming cover plus the timming cover comes now where near the valley cover

I did it on my 4.6.

I saw it in the book on tuning Rover V8 engines.
