In an earlier post Taffy mentioned there would be no oil feed in that head. At the time I thought that was a reference to the external oil feed I was intending to add. However, now I can see what you mean - there is no oil gallery in the corresponding location.
I assume there must be an oil gallery elsewhere perhaps running through a bolt hole? Will I be able to have this drilled for the 501 located oil feed or is this head swap just not possible? Going to need to address this before I go spending on parts. The 501 head has some minor damage so it will be a toss up between which is the more economical to repair or modify.
the newer cases still have the oil gallery drilled its just the heads that are different so as far as oil galleries are concerned you can out a new head on an old bike and its the same setup as a stock 04-08
on my 08 I run an external oil line from the oil filter cover to inside the exhaust rocker pin and have modified things there to direct the lube where i want it. as stock it was just splash lubed but i flog the piss out of my bikes on 40deg C + days so the extra oil up there helps
the 02 head has a complex oil feed system as stock and is required as the rocker arms run on bronze bushings
