Anyone hear of Diamond Power Pistons I found some 4.8 flat tops made by a company called Diamond Power. Not sure of how good there are so I would like to defer to some of the experts on here. They are only $100 for the set which includes the wrist pins too.
Are these any good?

Diamond Power is made in Mexiico not China. bought some of thier valves before, have not heard anything bad about their pistons. Some guys have used them with no problems they' are OEM replacement , nothing more . But you can get gm flat tops for $100 , pm me and I'll tell you bout them.

Diamond power also makes a full engine gasket kit with all GM MLS gaskets. Including the head gaskets. I put that kit on my Lq4 it was pretty good quality. If anyone's interested, I think it was around $150. Part # DFS4121.

OEM 4.8 pistons ARE flat tops.
