Engine paint color match?

I bead blasted the head, cylinder and engine cases. I painted the cases with HT Caliper Paint (cast aluminum) but left the head and cylinders unpainted. All painted surfaces were finished with 2 coats of Spray Max 2K satin. This is the result:

Probably not, I haven't loaned too many tools over the years, but it was in the hands of both my father and my cousin at some point during that period so who knows. When it's a tool that doesn't get used often after a while, you tend to forget the last place you saw it. I'm pretty good about that, but it's just been waaay too long on that one.
 
Thanks for the quick responses and great pics! I'm not a polish and wax kinda person, I guess I'll paint. I'm sort of inclined to go with the Duplicolor DE1615 Aluminum Engine Enamel with ceramic (whatever ceramic is or does in paint ) 500°F paint.

For those of you that have painted your vapor honed engine cases & covers.....
Did you prime before painting?
Was the vapor honed finish sufficient for paint to adhere or was "scuffing" required to roughen the finish?

Thanks,

After my cases came back from bead blasting, I washed everything three times in the parts washer that had a solvent based solution. Once dry, I then washed all the parts in hot water and dish soap. It was probably a few days later that I decided to paint so just before painting I rubbed everything down with laquer thinner to be sure there was no oil residue or finger prints. No sanding or scuffing required.

I did not use primer and just sprayed to light coats of VHT caliper paint (rated to 900F) directly on the bare aluminum. This paint needs to be cooked in the oven at 200F for an hour to cure the paint. I waited about 30 days before I used the Spray Max clear coat. Do not use Spray Max in an enclosed area and make sure your skin is covered and you wear a respirator type of mask and safety glasses- it's nasty stuff.

I tried that one as well as other coatings. Unfortunately, most of these coatings like Renaissance Wax are not heat resistant.

Next engines (CB72 and C77) will be experiments, one with paint, and the other one with ceramic coating. Our humid environment is aggressive, with salt on the roads in the winter.

If you want a good match, buy a small NOS part with the correct color, let it scan and paint.

Might not work on the cylinders, but I would think it should be fine on the covers.
 
Heat resistance goes as far as 100 to 130 degrees Celcius, the cylinder goes above it occasionally. Yes, side covers are ok.
