For some stupid reasons I am forced to replace the camshaft in my V11 sport -02.... I was thinking of boosting a couple of HP at the same engine rebuild and found a German tuning component for a repacement. The supplier asked if my head allows an overlap where the valves open 4.5 mm at the same time. Since my cylinder heads are not here for measuring, I ask this great space of bits and bytes, if this is possible, or is there a risk of valves hitting one other. The head is very standard an non modified. Would anybody have a head in hands for this quick measuring? Regards, Ari

I reconsidered. -59. 52 did not have the stamped sheet metal frame yet

Now I make a guess: 1952 ( ... the Olympics in Helsinki) It is a nice twin piston engine with common combustion chamber. 250 cc I guess again.

Austrian Puch, no doubt
