That is amazing work. Almost makes me want to set up CNC......but I'm having too much fun making mistakes and scrapping parts "the old way".

Can you tell us a bit more about the valves. Are these just the guides for the valve stems to slide in & something different for the actual valve seat? Kind of hard to make out scale or how it integrates into head.

 

[sbdtasos]

yes that is only the guides for the valves
as you will see on the photo i dont use valve seats
my engines work with this type with no failure

Beautifully executed. Great choice of finishes also. - Terry

 

[FKreider]

Wow, fantastic work!

Are the distributor and exhaust pipes 3D printed?? Will they hold up to the head without melting?

Anxiously awaiting videos of it running!
