What
do
you
mean
by
the
old
top
block
?

 

I all the bolts for the top half of the block are through the bottom 'girdle' section. You need to remove the oil pan to get to them. The timing cover has to come off of the front, too. Once apart, you will see some markings on the block and the crankshaft that you can lookup in the shop manual to find the correct bearing sizes (Honda uses colors rather than actual measurements):

 

Do not take the girdle/ main bearing caps fromone block and put it on another. The main bearing bores are line bored together and you can not mix and match.
