i didnt know that their was a difference and i ordered A pistons for my h22 swap, i have the pistons bought "320 bucks" with rings, and was about to put them in and read the service manual i downloaded and looked and i have a b block, would it hurt? the pistons is just a .010 difference..the pistons are between 86.993-97.006 and the b is 86.983-86.996. if anyone could tell me if this will ruin anything let me know. i was hoping to have the block together tonight...and this could set me back A LOT!

Just going by those numbers it seems like a pretty tight fit and tolerances. Worst case you may have to purchase different rings or do a slight overbore. I can't tell ya anymore than that. Try Honda-Tech, there's a thread in the prelude forum about it but it doesn't offer much help. However, I'm sure someone over there could help guide you.
