You are missing the spacer between the firewall and booster.

No spacer on my '88 K1500.

No spacer on my '88 K1500.

No spacer and the break pedal is in the proper height?

1988 K1500 regular cab

Vacuum booster bolts directly to firewall. Replaced booster ~20 years ago, new (rebuilt) booster bolted directly to firewall. Replaced booster two weeks ago, upgraded from "small" 1/2-ton booster to one from an extended cab--bigger booster, bigger master cylinder. Bigger booster bolts directly to firewall.

Easy to see the brake pedal touching the brake light switch.

1997 K2500 extended cab
Hydroboost unit bolts directly to firewall. Under-dash is totally different from '88; I can't tell what sets the pedal height, or where the brake light switch is.

The brake pedal is always higher than the gas pedal, on every vehicle I've ever driven. During a "normal" stop, the brake pedal gets pushed so it's still maybe an inch above the idle position of the gas pedal. I can pull the pedal "higher", but when I let go, it drops to the usual at-rest position where the brake-light switch is touching the pedal but the brake lights aren't lit. Gotta push the pedal slightly to activate the brake lights.

I'm thinking that if your brake lights work properly...the pedal is where it's supposed to be.

The brake pedal is always higher than the gas pedal, on every vehicle I've ever driven. During a "normal" stop, the brake pedal gets pushed so it's still maybe an inch above the idle position of the gas pedal. The brake pedal height is set by the rubber bumper the brake pedal lever hits on; or by the brake light switch. My '88 seems to use the brake-light switch as the upper limit of travel.

Maybe you're missing a rubber bumper under the dash, or the brake-light switch isn't adjusted properly.

I know my 92 has the 2 to 2.5" spacer between the fire wall and booster. The rod from the booster sets your pedal height.

Four studs poke through the firewall, nuts on the inside. No spacer.

Left booster is upgraded "extended-cab" unit, right booster is crappy, small, "regular cab" unit. Original booster on the truck was like the one on the right.

Interesting. So they changed something between 89 and 92 or the c1500 rcsb uses a different set up.
