    With a solid cam and valve train how does the oil get to the roller rockers? Is there a port in the block that oil gets pumped up through the heads and splashed on the parts?

    The rocker arms are fed from the cam bearings through the head and up into the rocker arms by one of the "middle" rocker shaft bosses (either #2 or #4 depending on what side head (pass or drivers).

    If your engine is on a stand, you can take an old wire hanger and straighten it out and poke it through the oil hole in the block and make sure that the tip goes into the cam tunnel through the cam bearing. This will make sure that the oil holes in the cam bearings are properly aligned before you put it all together (with the cam out). The general rule of thumb is that the cam bearing and hole in the block should not be more than half overlapped. If over half the oil hole is blocked by the cam bearing hole, you need to remove the cam bearing and reinstall another one with the holes lined up better.
