| RE: Oil Burning 390. Help!! |

Holley mainjets are rumored to be a perfect drop-in fit. There are many solutions, all pretty much home brewed, and all do a good job as long as they're not too loose on the OD and not so small the orifice can clog or restrict too much flow.
I seem to recall some folk saying a #60 jet or maybe a .060" diameter orifice in the jet (I forget, and it really depends on personal tastes anyway). Others say different diameters, and I'd probably opt for a slightly larger diameter until you get a specification from some FE'er you trust. I don't recall the specs of the drilled copper wire I use.
Just yank the rocker assy and drop it down the (1/4"?) oil feed hole that comes up near the bolt hole.
Also, you apparently have a 1968-71 vintage motor, based on your part numbers. You'd have to look at the date codes in the casting to narrow it down more. The "S" intake is also known as the "equal runner" intake, the smoothest idling and smoothest running intake of all FEs (JMO). They come in both 2V and 4V forms and are basically all identical and quite common from 1966-on. The only alternative is the very common "T" intake which was also available from 1966-on. Both are emissions design intakes which have smaller runners than '65-earlier intakes. Your intake may sit 3/4" taller than the "T" intake, but it's not a performance intake by any stretch of the imagination. Still, it's a good intake design. Your block markings are generic and could mean it's any block from 68-later. Ford got sloppy with FE block casting numbers from '66 thru '71 and even later.
