Exactly as above, pieces yes, kit no.
I like their engine enamel. It is VERY thick. I will offer one bit of advice though. While it brushes great onto cast iron, you are not likely to be happy with brushing their engine enamel onto smooth surfaces like valve covers. For that, thin and spray with a gun or air brush. I did NOT have good luck thinning and spraying using their solvent. The second coat would lift the first. I had much better luck thinning with plain mineral spirits and shooting the second coat when the first was almost dried. For added luster you can gently buff the dried paint (on sheet metal) after a couple of days.
The image below is my Mini engine painted with their BMC green engine paint.
