Painting an LS1?
Pressure washed the motor. And painted it with high temp engine paint aluminum and then clear high temp.
Used same paint on the accessories and painted all pulleys with black high temp and clear high temp.

From my build thread:
This weekend I decided to tackle cleaning up and painting the engine. First I needed to seal everything up to prevent water from getting in.
I removed the valve covers and removed the rocker arms. This puts all the valves in a closed position, which should help prevent any unwanted liquids from getting in.
Next I stuffed the ports with towels and used a quality (Scotch brand) duct tape to mask off all the ports and sensors.
Then I laid a tarp out in my driveway, rolled the engine out, and went to town with a few cans of engine degreaser, a scrub brush and the garden hose. These pictures were taken at various stages of cleaning.
On the last few clean & rinse cycles, I used Eagle One Mag Cleaner in a spray bottle from my local autoparts store. This is an etching cleaner that contains a few different acids. It did an incredible job of restoring the aluminum to a more uniform appearance. Once everything was degreased and thoroughly rinsed, I put a few fans out to dry things off.

Next I used some painters tape and masked off the heads, waterpump ports, and cam position sensor boss. Most of the other connectors were already masked off with duct tape from earlier. For the waterpump ports, I put tape on the old gaskets and used some bolts to hold them in place.
Finally, I laid on several coats of Duplicolor engine enamel. I used this on my old small block and it lasted 12 years and still looked good when I pulled the engine.
These pictures were taken as the paint was still drying, so it looks kinda splotchy but you get the idea.
Later this evening after rolling her back in the garage, I set the intake back on top and snapped these photos. Overall I'm pleased with how this cleaned up and I'm very happy with the painted valve cover, painted timing cover look. I wish it wasn't going to get cluttered up later with accessories, wires, etc.

I clean the engine with any needs to remove scale,grease and dirt. Usually pressure wash with purple power. Finish by hand and steel brushes. Usually just paint bright aluminum silver or silver hammertone.
