Can you tell me which red paint you used please? looks nice and bright, great job too by the way :) I'm painting mine red and looking for a very bright red engine paint.
The red was just a Hammerite rattle can sprayed over zinc primer.

Resurrecting this thread to add a question.
What are the simplest method using commonly available products for de-greasing and prepping an Engine Block for painting?
My block is back from the machinist and before it went I gave it a damm good clean up with Petrol and soaked it in a Citric Acid solution to remove as much rust as possible. It has been in the machine shops parts washer a couple of times between jobs but it is now soaked in WD40 and wrapped up so it needs cleaning again.

White spirit or thinners will do a good job of cleaning it too - then I recommend warming the block/head with a hot air gun so there's no moisture on it for a longer lasting finish. Etch prime and paint.
Yes I have read about warming the block. Ref Etch Primer, the paint shop said I did not need to use any primer with this paint but I do have some Halfords Etch Primer that I could spray on thin?

Cellulose thinner is very aggressive and a great final degreaser it also leaves no residue once evaporated, cheap as well.

Definitely use an etch primer... it gets a good hold of the surface and means you don't need thick coats of paint for it to get a consistent cover... The thinner you can put the paint on and get a good finish the better, and the less chance of it peeling or chiping off..
