I have read thru all the related posts already and now I'm not sure which front oil gallery plug to drill the .035" hole in to lube the timing set and bleed air? I always thought it was the center plug. Mike.

I don't like trying to memorize something, it's much better if it makes some kind
of sense in my mind. Think of it like this, you want the chain to cam gear surfaces
to receive the maximum oil, so you want it on the leading edges. Not on the chain
as it leaves the cam gear.
