I bought a set of these dss heads cheap from a guy who had a stroker motor built by dss. They are cnc ported and look very different next to ported mmr heads. The dss intake ports are massive and the step in the chamber in front of the intake valve has been removed. The mmr stage 2 flow great but I'm torn between finishing the dss heads of installing the mmr. What do you guys think of the heads. The pic where there are two heads the dss are on the left. Huge ports. The other pic is the dss chamber
