What do I use to clean the engine to make it look new

If those are through-plated-holes in the exhaust ports Ash, you are in trouble :)

No trouble ;) ..it was backed with a 1mm silicone rubber sheet
The fasteners/ cam bearing covers / alternator cover and camshaft were just old scrap items... note the cam has a broken off shaft that the auto advance fits on to... it was a perfect cam until DK shipped it in a polythene bag with no other packing/padding and the shaft broke off in the post where the dowel pin fits :( .

As I don't have access to blasting or washing plant I have to use James' brush and solvent approach. And time, lots of it. ...
When I restored my barn find CL450, I washed and brushed the unpainted alloy head and barrels with first petrol and then brake cleaner, I used a fine modelling brush to get in between the fins, while squirting in the brake cleaner from an aerosol can, held close up to use the pressure to shift the crud. Expensive, unless you can get it cheap, but it worked.
The crankcases I thoroughly washed in petrol, using a tin can and a small paintbrush, the old blunt screwdriver is for persuading old gunk between the fins to come out.
I then used, wearing a mask I bought online (that the wife now uses for shopping!), Magic paintstripper, with extra deadly fumes, applied with a brush, to get the remains of original yellowed laquer off where originally applied on the polished parts of the cases. Then I mixed up some baking soda I bought from the corner shop with a little water, and scrubbed all the nooks and crannies with an old toothbrush to degrease everywhere before painting.
When I was finally happy I used Simonize silver VHT from a rattle can. I heated the can in a sink of hot water as it was the middle of winter.
Finally, I polished the alloy cases on a bench mounted polishing wheel after getting the remains of laquer and blemishes out with fine wet and dry. I used polish from a block I bought at an autojumble years ago.
The (nearly) finished result.
Spitfire:
I spent many a happy hour with petrol, paraffin, Brillo pads, lolly sticks, Dremel with little wire brushes, cleaning my engine before painting it with VHT paint. It was worth all the effort in the end despite the stubbed and sore fingers.
Cheers

I like the creative use of house bricks and wooden blocks as an engine stand.
Mine is the Trigger version.
