spark plug removal
I have a stock 95 w/LT1, 112K. Looks like the original plugs are still in the engine. Would like to install new plugs and wires as part of spring cleaning. When I put the plug wrench to no 2 and no 4, they wouldn't budge. Engine was dead cold for about 3 days. Must admit I didn't push real hard, flexed a 12 inch long 3/8 drive breaker bar a little then lost my nerve. Didn't want to strip or break a plug. Am I missing something?
Sometimes that'll loosen em up

Run it only long enough to get heads very warm, not hot.
Considering that torque spec on the plugs for LT1 aluminum heads is 11 ft-lbs, someone apparently Gorilla'd them down for you at some point in the past.
When you get around to it, here's a suggestion for changing LT1 spark plug wires:
