I have some pistons and I'm trying to track the PN down. A fellow on eBay was the high bidder and now he says he can't buy them b/c my auction was not accurate. He says they are custom and not flat top pistons. They came from KB like this to the best of my knowledge.
Are these flatops?
Are these custom?
