It appears that there are drain holes, one at each end, near the valve springs, but then I am told there is no oil path through the cylinder heads. I'm chasing a leak and even with dye I haven't found the source yet. It isn't the valve covers or the china walls, there is no oil leaking above the exhaust ports.

Depending on the head gasket used, some guys forget that the head gasket doesn't come up all the way to the china wall and it leaves a gap. On some head gaskets, you have to put a dab of silicone under the head before you bolt the head on. That's an easy place for leaks to generate.
