The fact that the hf bottom end has 8 vlaves is how this whole build up works.
A- valves don't hit pistons with a stock si cam/valves. vtec heads will NOT work- too much lift and they will hit.
B- with no reliefs, it creates a LOT of compression, and thus, torque/power.

The extra compression gained from the lack of a couple tiny valve reliefs is not nearly enough to make that kind of power.

B16a is not going to get worse gas mileage unless you're always on the top end cam.

It does require premium gas... but it gets 30-some MPG. Try a turbo RX-7, sucking down a gallon of premium every 20 miles. Honda guys have it good.

That's one of the many reasons I still love my 26mpg non-turbo engine.

Not the first SiR?
The 90-91 motor?
10.2:1 compression.

Say what? Yes, all DOHC VTEC cars require premium gas.
