The stock 60V6s are all rated at rather low horsepower numbers. Given that the engine has a lot of potential, what exactly causes such low stock HP numbers?

WOT-Tech were making them for a while..... might be still.
but a word of advice is that pacesetter headers = BAD. horrible fitment issues along with a bad design.
30-40 from headers alone might be a stretch, but with some intake improvements(notably the large port UIM/LIM and larger throttle body), probably could see that, depending on what you start with.

A cam only otherwise stock 3400 can likely pickup 40HP +
It also depends on what 60v6 you're talking about though, gen1's have junk heads, gen 2's have junk heads stock but they can be ported to flow decently, but their LIM/UIM combo kills most porting gains. Gen 3's flow good stock but can really flow with good porting.

early "Small port" gen 3. 94-99 3100's have smaller runners as you can see in this picture: (hopefully it shows up)
Those 3100's can gain some noticeable power by swapping to a large port lower and upper intake from any year 3400 or a 2000+ 3100.

you'll also have a few smaller issues to deal with due to being a 95, but they really aren't that significant.

Just do what I didn't. Spend the money on ported 3400 intakes and have the hole for the coolant by-pass tube tapped to work with your stock tube.
I'm not sure what "level" of porting is ok with OBD1.5. That is if you want to avoid tuning.95 Beretta 3100 with 3400 intakes and TCE TB
