These were done last night. I spent about 4 hours alone total on the bridgeport cuts on an already done set of street ported front and rear irons. This is the same half-bridgeporting scheme I offer to folks who do T4-style setups and want more mid-range and high-end power that still want decent street drivability. The bridgeport width and length (heighth) is kept conservative while the same types of radius'ing and other modifications are made to help 'accent' its flow as an additional intake port as opposed to just having a cut made straight down into the iron.

Anyways, yeah I was pretty pissed off when that happened. It happened at the tail-end of finishing the second eyebrow cut. I think I was edging up the port closing timing on the eyebrow when I did it. My lower back was killing for about 20 or so minutes from being hunched over for hours working on it whilst standing the whole day so it had something to do with it. The housing is getting lapped after this is all done so it won't be an issue; still noticable in the pictures, though.

I just tried posting on this but the server whacked out. My apologies for a repost.

My projects always get fucked in the last 5 min if they get fucked at all.
NIce job Brian.. Pix look great.
Typically how long will the bridge hold up?

Yeah, that always gets me when it happens. It's difficult to avoid sometimes when you've got an 1/8" grinding stone whirring at over 25,000+rpm; it wants to grab on to anything and skip around.
How long will that kind of bridge last? I'm not honestly sure but I wouldn't bet it'd die any sooner than your average stock or street port. That bridgeport is quite conservative -> the bridge itself is still quite thick and wide. I'll measure the thickness of it tomorrow and tell you but I believe it's about 0.225" wide or so, or right at 1/4". It's fairly meaty compared to those uber-thin on es that you may've seen crack.
