I'm looking for some input concerning the rocker arm modifications Gord McMillan did the article about. It was about pressurizing the rocker shafts by plugging the overflow pipes with a metered orifice.  He then advised drilling additional holes in the shafts.

Would one do this in addition to cutting the groove in the camshaft? Instead of cutting the camshaft groove? Or is it even necessary if you have a properly grooved cam with hard cam bearings?

Thoughts,comments, observations???????????

Thanks
