A properly engineered an executed bridge will not eat seals and should not significantly shorten the lifespan of an engine.

I say "should not" because I don't know anyone who putters around in a bridgeport like its a daily driver. They are typically hard on their cars and when they are not beating on the car it is sitting (the only thing worse than beating on it). So yes, there does seem to be a positive correlation between bridgeports and shorten engine life, however I think one would be hard pressed to establish a causal relationship , assuming the porting was of reasonable quality.

That being said, you can obtain a certain level of brap with a large streetport, although not quite the same, it may be a compromise you are more comfortable with. If you are insistent on a bringe, consider a half bridge, which leaves the primaries alone (aside from perhaps a streetport) and bridges the secondaries which helps slightly with idle and low rpm manners.
