i feel like a tard for asking but.....

im looking in to buying this:

a used Darton Sleeved H23a1 block. It lost a rod bearing & I was planning on rebuilding it & machining it for a H22a4 (55mm mains) crank for safer high rpms, but have decided to take another direction (sell my Lude). It's a bare block, except for the water pipe, oil cooler, & oil squirters. I also have the crank & a H22a4 girdle. Cylinder 1 did get scored a little due to the lost bearing & is probably no longer any good at 87mm bore. This block is for those interested in building it at 87.5mm or larger bore.

now if i get it bored out to 89mm do i have to resleeve it??
