The big  advantage with the lathe is that with bar feed, you have something 
to hold  the part you are making.  With a mill approach, there is a large  
expense ( and headache ) in trying to figure out how to hold that funny  
shaped part.

In our toy car business, we have run  thousands of button heads for the 
little engines, mostly all hemi-heads,  with  various double bubble, 
tapered, 
low compression, high squish  ... just a minute or so changing programs for 
different test  heads.

I think a good setup for the new heads would be 3  injectors per side, with 
a 
central mounted air throttle, or 6 Mikuni s,  with hydraulic or pnuematic 
linkages on the throttle bodies.

just  some thoughts, ken campbell, deltawerkes 



I had shown my images to several Fastvair contributors (including yourself) 
 with the idea of using a mill to machine the head rather than turning it 
on  a lathe, then milling it.  One or two of these people voiced their 
approval  (it's been 50 years since I had machine shop in high school, and 35 
years since  I took a course in night school at the local tech. school; they had 
CNC  machines, but that was only for the advanced students.)
