Cam around 240@.050
As I said (50 years ago?), that narrows it down to perhaps 20 or 30 cams.
What nominal duration?
What LSA?
What installed ICL?
Single or dual pattern?

The reason being is to try and keep some quinch in the combustion chambers

Ideally, the dish would be close to a mirror image of the chamber outline (and flush under the head's quench ledge). IMHO the floor need not be flat if you have enough dome thickness - deeper under the intake position @ .200".
