Thank you Jan 72 These are the numbers needed. Engine case opening 100mm and opening in head opened to 105mm. Since as already noted I have a set of 1.7 heads and now know that the cases are good a search for standard cylinders. Too bad the specs you gave are not in spec sources but maybe they are available to someone now. Thank you Dave for watching. Found what we needed to know. Me and my dog Sophie Billy Thanks for everyone that had interest.
