I suppose material was not changed to later 1725 hardtop Alpines
(Hunter/Vogue etc. types of 70's ??)

So 95 or 98 unleaded is suitable for both 1600 and 1725 engines? (I have
used 99 with sodium additives for last 5 years, when 99 leaded was put
under an enviromental tax in Finland).

I am going at least to build a 1725 with a mild street tune, with 98
unleaded it might be posseble to cut the head slightly down?
