Radial- Diametral Head

[Hans Hintermaier]

Hi head builders,
because of the big resonance for the radial- diametral head of 
"Apfelbeck", I put the GIF images on the web.

The ISBN's and book titles are
Ludwig Apfelbeck
Wege zum hochleistungs Viertaktmotor
ISBN 3 - 87943 - 578 - 2 
and
L. Apfelbeck / H. Weichsler
Ventilsteuerungen fuer Hochleistungsmotoren
ISBN 3 - 613 - 01272 - 3
Both have ~200-250 pages and cost around 25$

He discribes many simple ways to tune and new-build an engine.
40 valve curves for different purposes are added.
Regards
Hans
