XK twin cam 4.2 cylinder head valley paint

[RobXjcoupe]

Just re-built this cylinder head and I want to paint the valley like the e-types had. My question is do I etch prime the aluminium first then find a suitable heat resistant paint or are there heat resistant sprays paints available incorporating an etch within it?
I don’t want to slap any ole paint on that will simply peel and flake off. I would like a gold colour similar to the e-type if possible

Thanks in advance for help
