Things I learned this weekend
If your car has over 100,000 miles on it, you're way overdue for changing your injector O-rings. All 12. The 6 in the lower intake were grimy on mine, and the 6 in the fuel rail were dry and cracked (on the verge of leaking fuel onto my intake). This is at only 80,000 miles.
If you're going to drill bypass holes in a 180° thermostat, the size of the holes is very dependent on the climate where you live. With the mild climate in Oregon (50°F today) four 1/8" holes was too much. The car is running an average of 169° with the heat off. I'd suggest four 1/16" holes in similar climates to mine, and two 1/16" holes in colder climates. You can always go back later and make them bigger if you need to.
When doing a SC rebuild, drink plenty of beer. It actually makes it fun. It also helps when it'* cool out (45° yesterday) to keep the sealant in your pocket to keep it soft.
