Heat is what pushes the piston down, don't throw it away. Daily driving with a cold stat will just use more gas. Try decking the block, use the tightest quench you dare and if you feel like fiddlin' with stuff cut Singh grooves in the pistons. Be sure there's nothing like a sharp edge in the chambers or on the piston tops - no sharp edged valve pockets. That all won't let you run 87 by itself, but it'll run better than it does now.
Knock sensors are old tech now. GM ran 9:1 on iron headed engines in the '80s that way, on 87. Sensor setups have to be tuned to work with each engine.
And never believe anything you read ;-)
