Assumptions made before proceeding with items below.

Crankshaft assembly

Crankcase assembly


Test assemble for measuring


Cylinder head

Final assembly


Some/many of these items could be done in different order.

More could be done that I have not mentioned (i.e. bore carb venturi to max, bore intake manifold to max, shorten intake tract length to minimum, etc. etc.). This is only a brief list of the items that quickly come to mind.

Many of the "settings" should/could be personal preference (or the preference of your engine builder): port heights, combustion chamber shape, cc's, carb hole sizes and carb settings, etc.
