I have a b16a2 block fresh from the machine shop.I was going to have to bored out because of the pits in the cylinder but i have moved to a h22 instead.The machinist told me the block was fine and the cylinders were not cracked they just need to bored out to take out the pits.Just .5mm should fix it.I have all the main caps to go with this block.The price is 80bux. If you dont like it make an offer.Its just taking up space here.
