Speed Pro L2481F Pistons

[Buick Mark]

I just bought a set of Speed Pro L2481F forged pistons to replace the Forged TRW's in my GN due to the wrist pin oiling problem they have. I ordered Forged Speed Pro's, but the underside of the piston looks like a casting, they have a rough surface finish like a casting, NOT the smooth finish of a forging. The part number on Summit's website says there forged, and the part number on the box and reciept all match. These new pistons have the coating on the skirt and the liteweight pins. Anybody else notice the rough finish on the underside, or am I worried about nothing Mark

Mine look like that too. Even worse, there are tiny nubs that look like casting marks on either side of the rod.

What are you going to do about the oiling problem.
Any info on the oil mods???
Thanks
P.S. mine look like that too.
