After a few months , I received a large package from Bob Walla . He found all the missing parts for me and sent them to Switzerland together with 2 new cylinder heads . The joy was great , better than Christmas and Easter together
. Now I have assembled the engine with the crank drive , connecting rods , piston and camshaft as a test . The heads and the intake mounted as a test , everything fits . With an adjustable push rod and soft valve springs , I then turned the valve train and measured everything . To my astonishment , the exhaust valves are not lined up in the engine block . It even has enough play that nothing happens . I told Bob that I don't value as much horsepower as possible at 6000 rpm , but rather a good idle and enough steam from the cellar . A Comp cam 48-802-11 is now installed . He then sent me the matching pushrods . After I disassembled everything again , I milled the cylinder heads at the front and adjusted them so that they look similar to a normal cast iron head . Not that I don't like Bob's logo , but for the traffic registration at the road traffic office . If they see that you have mounted aluminum heads , you have to bring a performance diagram and reinforce the whole chassis . After that I brought the block to my workshop
