Sorry it took awhile to get back to this, and i didn't mean for it to be in Fleetlines's thread. I thought both sets were low compression, when I went to look at a new set, they were full of valve reliefs and had the large chamfer on the edge. I wish someone made a cast piston with a true flat top like the OEMS were. These look to be universal to me. Thanks for the information, Joe.
