Oil Pumps

[ScotiaFE]

Looking at the Figure 1 there, there are only 2 oil feed passages in the heads(1 per head)?

Here is a good overview of pumps and other oiling options for the FE: http://fordfe.info/Forum/Oil.html

Correct, one oil passage to each head and that feeds the rocker shaft.
The passage in the head is where you put the restrictor in.

Funny thing about Edelbrock heads. The oil return areas are smaller than Ford iron heads.
I did a little blurb on opening them up a little bit ago.

Reading through your thread, I'm not clear on what you did to the oil drainback holes.
Did you drill them out to the smaller end to 1/2"?

Reading it myself I'm not clear either. 
I would have drilled the oil return hole bigger for sure.
At least out to 1/2".
Next time I have the covers off I will measure and rewrite my gibberish.

You also want to smooth out the little valley at each end. A small burr in the die grinder
will make quick work of that.

   I can't understand the infatuation here on restricting oil to the heads/rockers.  Oil draining from the heads through the designated holes at the ends of the heads is relatively variable at low rpm/low oil pressure the oil held in each head varies from zero to a few ounces as it drains away to I'd estimate a quart at max pressure/rpm. Once the max level is attained "in the heads" it simply flows in bulk over/through the intake down into the lifter valley. It can not exceed that set level since it's a waterfall.  The most oil that will ever be in each head can never exceed 1qt. The two quarts being held in the heads is a given.  When filling the motor with oil you need only to plan on two quarts residing in the heads when the motors running.  I understand valve springs especially when running high spring pressure and high lift get really hot (I witnessed Smokey's Spintron heat/spin the springs as he sent the vales into float). There's graphs around that show how much spring pressure is lost per unit of heat in the springs, obviously there is also a relationship to heat and valve spring life. Oil is essentially the only way to remove heat from springs - if there's nothing but mist around the springs get hot. One example is burning the hell out of your finger tips when bending a paper clip to break it.  With Teflon seal's oil is not getting past them.
    Finally if you've ever studied FoMoCo FE rockers and Shafts you know there's numerous holes and passages that index to jet oil at the rocker tips, spray the springs and pressurize the rocker/shaft bearing surface. You start reducing all that engineered oiling and

Perhaps it's asking too much if one would carefully read this and also understand it.
