Nobody mentioned Total Seal gapless rings. I have used them in other engines before and liked them, now I decided to put them on my 230. (Second rings). I did not bore the block oversize, although it kinda could have used it. Its a little loose but at the time I wanted to leave room for more expansion in case I slap a turbo on it. Then compensate with gapless. Haven't fired it up yet, we'll see.
