Can someone tell me whether 64 and 65 200 heads are compatible with 66 blocks ? Are there any differences I’d have to deal with putting an earlier head on my 66 block ?

pretty much any 144/170/200/250 head will bolt to any year/size block. There would be CC differences, intake log sizes, carb mounts sizes, and possible valve size differences..
200 to 200 in those years should be very similar, if not the same.
