Yeah I have a facelift block 25 6 k1 as you say. but I was under the osumption there was 2 different brands of pistons used either mahle or ks and one of the brand requires the pistons to have the bottom shaved to clear the crank counter weights.

Thought that may be the case if got the ks pistons with a bit of skirt on them, I think the mahle are pretty flat about the base of the piston.

Stick with the mahleones if you don't want to shave the skirts

Didn't you say you have a block with 25 6 k1 on it, if so the pistons from that block will do. If you still need some i might have a set just need to find them.

You can use the pins that you have got or the ones that came of the 320 block
