A full "J" bridge port with stock apex seals presnts some insurmountable problems. If you cut open the rotor housing to match the port in the iron the small corner piece will fall out of the slot. If you have not ported the center iron yet, you could do a conventional bridge port and install the apex seals with the corner piece against the center iron. Or, you could leave the center iron stock, or, you could street port the center iron. With no rotor housing mods against the center iron there is no problem.

If you have "J" ported all of the irons, then you need a solid apex seal of some kind. Steel, ceramic, or carbon. Or another center iron.
