See that are notched at borders, they are for use on big valves square ports heas or smaller valves cathedral ports heads? The mark on top of piston is from or for?
They have never been out of the package aside from that one to take a picture. I believe they would clear any of the Cathedral or LS3 Family of heads. I was planning on using them with a Magnuson 2300 TBSS set up and a set of Ported 243's. Built a Mahle Flat Top plus a set of TFS 225 CNC Heads instead. Topped with a Mamofied LSXRT. I have the Formula and decided to back off the 9-7X Aero Build and be a little more sensible. Selling stuff in small groups so I can keep up with tracking and people.
Yes they are Forged. Everything is new in the box as made by Diamond. Check that part number on the rings, I believe they are 180 alone. I listed everything I could and the only piston that's even been out of the packaging is the one in the picture.
