OK, one rummage later and I do indeed have some of what I take to be the earlier type cams, and have one exhaust and two inlets with slightly different lobes which might be what you need.
As regards the cams in general they ARE very similar to the “S†cams, the major physical difference being the additional shoulder on the outside face of the cam gear on the early cams. This suggests that a set of Bullet cams, even Indian cams, would at least get your engine to run with a suitable â…†thrust washer to take up the excess end float.
Of the two inlets both seem to have identical base circles and flanks of the lobes, only the one on the right has quite a point to the tip of the lobe, the other has about 1mm less lift, is more rounded and is showing some sign of scuffing which I am guessing is down to wear. I suspect that they would originally have been identical. Have a look and see what you think.
If either or both of these is any use to you, along with the exhaust which has a bit of pitting on the lobes but still looks usable, not much sign of wear, drop my spam trap e-mail account a line.
b44ea AT hotmail DOT com – lose the spaces and replace AT and DOT with the approriate punctuation.
Another option if your local cam grinder has the capability is to use a set of Electra-X cams as blanks and get some new ones ground. The lobe on the Electra-X cam is a similar shape but larger all round including the base circle. You would stil need to fit thrust washers.
