Mmmm bridgeports 
You don't need to build the motor to spin up to 10k rpm though. Even with a stock redline using a bridgeport can be fine.
The guy asks if a 1/2 bridge is just doing a bridgeport with 1/2 sized new ports. Doing a 1/2 bridge means you only bridgeport 1/2 of the 4 intake ports (2!).
You can easily have full boost by 5000 rpm... most guys with bridgeported 13B's and large turbos will hit their full boost (over 20 psi) around 3500-4000rpm.
He wants to make 500 rwhp. "Easily" done with a half bridge 13B. Large properly sized turbo, 1/2 bridgeport, and 20-24 psi and you are over 500 for sure.
I didn't want to sign up as a new member to say this though...

What i was trying to say...
False Halfbridge: the new port is 1/2 the size of a regular bridgeported
True Halfbridge: 13b has 4 ports, only 2 of them receive a bridgeport, and the other 2 receive no port, or a streetport.

Yeah I knew that stuff, I guess I just worded my post wrong.
