In need of 2nd over pistons

Hey all I’m in need of a set of 2nd over pistons and I’m about to purchase them from heidentuning.com.
Before I go ahead I was just seeing if anyone has used them before and can tell me how accurate they are to 75.50mm and if they are brand new
Piston Kit 447 Type Oversize 75,50 2nd US Type.
Thank you in advance!

What about

I would be more concerned if the weight were the same. As far as accuracy the person doing the boring will adjust the bore to each piston. Heiden is probably suppling a quality piston so you should not have any problem with them. ALot of the guys have been using the pistons form cruzinimage and have reported good results. I would let you wallet decide.

Thanks gents! I ended up going with Heidentuning as the delivery is much faster to Australia and I must act now while I’m keen .

cheers!
