B18 head identification 1800

This info is what I have:

B18A (1) 1962-1964, head height 88.0 mm, compr. 8,5 : 1
B18A (2) 1965-1968, head height 88.0 mm, compr. 8,7 : 1

B18B (1) 1961-1963, head height 87.0 mm, compr. 9,5 : 1
B18B (2) 1964-1966, head height 86.2 mm, compr. 10,0 : 1
B18B (3) 1967-1968, head height 86.2 mm, compr. 10,0 : 1

Is *suppose* the difference in compression ration between the years is due to head gasket thickness? I haven't been able to figure that out yet.

Cheers, Ben
