Hey all ive brought some ATR pistons and rods to go into my a5 and what i'm wondering is will I have to resleeve the head for them to fit or will they just fit? And will I need new crank seals and if so where could I get them from?

Straight fit mate as far as i know, and putting in new gaskets and seals is always advisable. Where from, well some people will say Honda themselves but im sure there are websites that sell them, ill try and search in a bit for you.

Don't you have to be mindful of the oversizing? Some pistons are A's and some are B's to accommodate variances in manufacturing tolerances. Your block will have a stamp on the top of the short block at the top right (as looked at from the front) which will say AAAA or BBBB (or a permutation of); you need to ensure that the A pistons go in the A cylinders and the B's in the B cylinders.
Personally, I'd only trust Honda crank seals, having just bought some myself (even though I have spare aftermarket) they'll cost about £35 for the pair, though the flywheel end is a bitch to fit correctly.
