Been a while, getting back to the 2.9 rebuild.

Hi all, it's been since last June that I was tearing the spare motor apart for a rebuild.
The bored, cleaned and painted Ford blue bare block has been sitting 'till now waiting for me.
Finally got started this week-end. Verified main brg oil clearances and now the cranks in. Checked fresh bore/piston clear., new rod brg./journal clear., and all 24 ring end-gaps. All is nice... shop did good work.
Need a ring compressor tool, so I stopped for now, But...
BIG QUESTION !
I have a Federal Mogul, Sealed Power premium rng set which I think is supposed to have moly coated rings? ? (Something like that).
Anyhow, reading the directions, I'm not sure which ring is the top and which is the bottom comp. ring.
There's 6 rings that are dark gray all over EXCEPT they have a bare metal, dull metal, not shiny like chrome, look to the ring face. They also have a band of yellow and band of red paint on them.
Then the other 6 are dark gray all over...even the ring face. They have a single band of yellow paint on them.
So, I'm thinking the dark gray is a moly coating ...6 rings coated all over and 6 coated everywhere BUT the face.
Now the instructions say, " Install bright face, (chrome or moly), compression rings in the top groove if supplied".
Ok,... "bright face" ...... well 6 are a dull metal look...(thats not "bright" in my book), but the other 6 are dark gray.... (also not "bright" in my book).
What's up with that?
The rings are all the same shape...rectangular. All have a dot on one side to show what side goes up.
Anyone know ? ?
Thans guys, Dave
