Solid skirt pistons need more clearance than the split skirt style originally used by Ford. Using the clearance originally specified by Ford will cause potential failure if solid skirt pistons are used. The Ford specs are for split skirt pistons. I too would recommend Silvolite pistons. The Chinese pistons need more clearance than specified on the packaging IMO.
