To use 998 pistons on an 1100 crank, according to GR you face around .140" off the pistons, you do not `chop the block'.
But by all means deck it a few thou to clean up.
In the old days, (when I was a wee lad) cams were usually identified by their timing figures.
eg Waggott Cams, Bert Jones Cams:
18/58
20/60
23/60
35/70 etc. etc.
So you are probably (maybe) talking about a 20/51.
If symmetrical (ie single pattern for both lobes) the full timing is 20/51 inlet, 51/20 exhaust.
If a single pattern cam it would have 251* of advertised duration, and 40* of overlap (both valves open at TDC).
This is not exactly a wild cam- the exhaust timing of a Morris 1100 or Mk1 Cooper S etc is 51/21.
These days the timing alone does not give a full picture of what the cam can do- valve lift is important, as is the lobe shape.
I would be going with a recognised cam grind that is known to work well in an A series. There are plenty about, local or imported.
I like the local ones.... Russell Engineering gets my vote, but I run a Tighe 104 cam in Barney (because it was in there already).
Other locals-
