Does anybody make an LA style rocker that oils through the pushrods?

I have a 5.9 Magnum shortblock with 4 inch crank and Icon forged flat tops in it. It is -0- decked and with the magnum chambers it would push 12.9 comp. I was wondering if anybody made a rocker for the LA style engines that oils through the pushrods? if so I could use my Eddelbrock heads with the 65cc chambers and drop my comp to around 10.8 with some thick head gaskets.
