Is there any thing that can be done to improve the oiling to the cam and lifters?  We did an engine break in run on the dyno (25 minutes) and post run inspection showed that the cam lobes were damaged on three of the center cylinders.  Would adding a couple of grooves off the center cam bearing help increase the oil splash in that area?  Or is there an oil galley that could be tapped into to add a spray bar?  I am running an Isky (Y-280-I-11) cam with Mummert heads.
