318 with pop up pistons and 302 heads?

If the piston is out of the hole .015" and measured correctly, then the dome is over and above THAT. The dome is not considered when measuring deck clearance, only the flat part of the piston head. So, in order for an accurate answer, we need a piston part number and specs including the compression distance. A part number would be great, then we'd be on to something.
