Ta eric has it. exhaust side has definitely been gasket matched. Intakes are pretty much on the money for stock. On the intakes you might see a bit of core shift offset and or a bit of a gap at that point in the divider between the ports, otherwise they're a nice casting. are these a match set of heads? the one image of the intake does actually look like it has been worked, the second pic looks stock. they may have been gasket matched as well. the SD heads respond nicely to shallowing out the radius on the short turn going down to the chamber.
