Au xr8 ute rocker cover clearance

[jono11]

Was wondering if anyone could help
Have got a crane cam 2031 in my ute yellow terra 'street terra' roller rockers and having trouble with clearance on the factory rocker covers does anyone know of a part number of tall rocker cover that will fit efi engine because of the manifold?

Need to get a phenolic spacer for it ,lifts the inlet manifold up , various sizes 1/4" usually does it or if it just touches it double up on the cover gasket

Are your referring to the rockers touching the valve covers? Some roller rockers will touch, you can usually just give the oil filler baffle a bit of a bashing to create the clearance required.

Yeah doubled on the gaskets and done a bit of modifying on the covers where they were hitting but wanted to change to a taller one just for peace of mind really plus will look a lot better than the factory windsor ones thanks for the replays ��

Does the phenolic spacer change anything performance wise?

It's supposed to help keep a little bit of heat out of the upper manifold, and increase torque slightly by increasing runner length.
