6 ports with a halfbridge?

When a bridgeport or halfbridge is done on a 6port 13b, are the 5th/6th aux ports left to function as normal, opening up at higher rpm, or are the left closed, so the engine is basically a 4port with a bridge. I dont notice any difference if the aux ports are open or closed.

thanks.

If you're not noticing any difference when the aux ports are opening, then maybe they aren't. When they open on my FC, it's like the 4 barrels kicking in on a carb. On a 6-port, I would bridge the aux ports only. That way you keep the streetability, but have the extra power when the aux ports open up.

Of course the primary and secondary ports should street ported.
