full bridges and half bridges use the same template. A lot of the major companies have templates so it shouldn't be too hard to find.

You can get 350+ on a good streetport with great driveability. A half bridge sounds awesome though (that's why I posted a video) with a little compromise in drivability but quicker turbo spool and more power (need a bigger turbo for it too to get the most out of it). BDC is a good guy for porting, building and advice.

Without knowing the shape of each exhaust it's hard to say.

The street template (it's basically a RB template) moves the exhaust down a bit. This will hit the turbo harder and increase spool but will hurt you in the top end.

If the race template moves the exhaust up and generally makes it bigger, this is best for a high RPM engine and bridgeports.

Your BNR stage 4 is too small for a bridgeport.
