LUK recommends a VERY (stress VERY) light coating on the splines. It is easy to ruin your clutch disc by putting too much on and having it fling out.
I don't have and answer to your question as I used the supplied lubrication that came with the clutch kit.

The technical article in this site, speaks about the use of grease on the throw-out bearing tube and the clutch spline. It also speaks about the improper type and quantity of that grease. BUT, it doesn't say what grease to use.
Am I correct in assuming that Duke believes that GM does not recommend grease at all?
But that some of you (allcoupedup) actually have a Mfgr's. recommendation for using grease?

The ID of the throwout bearing has a shallow groove in the bore that should be packed with grease and a light coat may be applied to the bearing retainer tube that the throwout bearing slides on. Also the groove on the throwout bearing that the clutch release fork engages into should have a light coating of grease. Use grease sparingly and use a high temp good quality grease. Other than that and the pilot bearing, no further lubrication is required.

Pilot bearing!!!! I thought it was sacralidge to put grease in the pilot bushing. 
As I've heard it explained here on the forum, The grease gets hot, burns, hardens then plugs the porus holes in the bushing material not allowing the oil-lite impregnated in the bushing to leach out and lube the shaft.

You are worring too much about this. Like I said earlier, 30 years ago I was a lubrication engineer (AMOCO) assigned to the automotive plants in the upper Midwest. GMs transmission plants (Muncie, Saginaw, Borgwarner, etc) shipped the units with grease on the splines to protect them. I supplied them a moly-lithum grease.
As Duke said, you really dont need grease on the splines. They do not move and are not a precision fit where the splines pass thru the clutch disc.
The pilot bushing (end of crank) and throw out bearing internal and fork groove do need little grease...use this same moly-lithum. Buy it at any auto parts store for a couple of bucks.
I have run my 61 for 38 years about 150,000 miles and have changed clutch assembly 3 times. After I apply a little moly-lithum grease in the pilot and throw-out, the residual grease on my finger is probably just about the right amount as I grasp the spline wrestle it into the bell housing
It wont affect your clutch, moly-lithum has drip point or melt temp of 370+F. If the temp on the spline or throw out bearing gets that high, you have a MUCH bigger problem caused by some other failure.
Now you know more than you ever wanted to know about grease. Hope it helps simplify your question.

My LUK repset came with directions and a small tube of lube.
The directions said to lube the splines but NOT to lube the inside of the TO bearing becuase the particular one I was using was nylon. What I do know is I follow the manufacturer's recommendation for proper instruction!
