yeah 45's are to big the smallest practical choke size for 45's is 34mm. 34mm at 1 choke per cylinder will be good for about 400cc per cylinder.
you only have 372cc per cylinder i wood suggest 31mm chokes or 32's as the max
so 1's thing to do is to sell the the 45's and by 2 x 40's dellortos and get 31mm chokes wen it comes to chokes for street car 1 size to small is better than 1 size to big.
BUT needle valve ' float level ' main jet 'emulsion tubes ' air corrector jet ' accelerator pump jet ' idle jet & venturis must all be the right size.
then you will love these cabs do all of this in is worth it.
in my opinon without a cam the cabs will not make a lot of difference something like a wade 240 grind is good for street and springs must go now.

I am starting to like the idea of keeping my kb10 with the original engine number the problem with the a10 is it is only 998cc,s what can be done about this and only 3 bering crank.
so we cant fit a12 or a13 or a14 crank or can we ?
can we get more capacity. what about a15 head, it has bigger valves and oval ports
