Well John, you exposed me. I am sucker for looking cool under the hood, and
anywhere else on the car. (As long as its period additions) I liked the look
and felt it could only help not hurt. Had no conscious view of improving oil
flow to the rockers. With everything new who needed to worry. Wish I could
sit here and pretend I know as much as the experts on this list. I guess now
I'll have to pull my hat down and shuffle away.

rebuild (9.5:1, late cam, ported & lightly polished, new seats and guides),
and sitting at a stop light on a warm day I would be very embarrassed by the
large cloud of blue smoke engulfing the cars behind me (of course, I could
claim that it was part of the mosquito-abatement program...). Like Alex's
car, pressure is 75 cold, 60-ish at speed, and 45-50 at warm idle (which is
around 1000 rpm - I've got a slight vacuum leak somewhere that hasn't been
annoying enough to track down...) I asked the machinist who did the guides
& seats and he reminded me that there are no stem seals, and that removing
the external feed might be worth a try. I did, and the problem went away
completely - surprised the heck outta me as I was ready to pull the head and
go beat up on the machinist. So the bottom line is that it looks cool, but
really isn't necessary on a healthy engine. If you've got worn rockers or
maybe low pres!
> sure then it could be a temporary fix I suppose, or if you have stem
seals (not 'umbrella' seals) installed, then it probably would be just fine,
and you'd get plenty of lubrication up there. The downside of that has been
mentioned in other posts.
