The heads... Well right now its a very simple design. I made the sketches in a simple fashion so I can go from 60 degree to 120 degree and from 1.5 litre to 6l without rebuild errors. When I have settled on specifications I will try to make a head with more features and I want to make it as light as possible.

Thats good sense. I assume you have dimensional relations. Thats a lot of effort, you have my respect. For me to change my designs that much would take a long time correcting each construction step, but I would expect smaller changes (boring/stroke/valve sizes etc) would be slicker.
