Unfortunately, the painting did not turn out as well as I had hoped. Oh well, this is not a show truck, and I surely will not be polishing the valve cover. I ended up using a VHT primer, followed by VHT GM Flat Black and VHT clear. However, I let the flat black sit overnight as I misplaced my 1FZ-FE sticker at my buddies house. I re-sanded the valve cover and applied a Duplicolor Semi-Gloss Black Enamel with Ceramic. I think it is a better paint, I just did not take as much time to get it looking good. The Gloss Clear really makes the black pop. The paint will not cure until heated to 200 degrees. Resists chemicals and temps up to 500 after cured.
I then sanded down the lettering for a natural look using a flap disk on the Dremel, followed by hand sanding to smooth out with 320. It is the 320 that scuffed the black up. In all honesty, no one will probably notice it too much unless you get close. Some of the sanding I did scuffed the area meant to be glossy and I just was not able to get as good of coverage as my baby was crying, my 7 year old was wanting me to play in the snow, and my wife is pissed that the LC is not done yet and I am worried about how the "engine paint" looks.

Overall if I was really unhappy with it, I would do a light sand and repaint but it will suffice for this time.
Got the starter out and will get my EGR block off plates made up this weekend. Then I will work on my Fuel injectors and start putting the old Mountain Goat back together.
Notice the paint looks hazey.
Edited to add paint color.
