almost none of your questions can be answered reliably, except that a bridged-PP engine is a very high revving engine and normally built for either show or track/drag use. it's not a street friendly port engine.

i will say that most engines built with such a radical mindset fail on multiple levels and are generally built for show. high revving engines need to be balanced and run a light anti wear seal such as carbon, which requires frequent rebuilds or ceramic which is $$ and where most people skimp, since balancing and ceramic seals alone paired is a $2kUSD expense, then you need a scatter shield and light flywheel, it adds up quick.

overported bridges do not have a long lifespan. a proper dual step bridge with flipped seals will last much longer for maybe .5% less peak power. it's simply not worth it to port a bridge til the corner and side seals are riding on a hairline sliver of the iron..
