The small holes are to help burp the system , if you put in a new 195 stat you can drill a 1/16" hole in the inner rim of the stat to help with this...

Low running temperature
I know this is not normal but my 87 L98 runs at around 158 degrees. Is'nt normal operating temperature about 180 deg . the coolant light comes on when i first start it and Ive topped off the rad. and it still stays on. cant seem to be able to find the problem with the coolant light of the low temp running.
Any ideas?

You found the secret that all vette owners want to know. How to make the engine run cooler.
......
But actually, it sounds like the thermostat might be stuck in the open position.
When was the last time you changed the coolant and stat.

I originally said Baloney also, but after I put 2 holes in my stat I never needed to jack the front up and burp the car again. The 2 holes allowed the air to burp without going through that whole process..Alot of the stats now come with holes already in them.The new Robert Shaw I just purchased has holes..WW

Are you sure the car is actually running at that temperature? You could have a defective coolant temperature sensor or display.
My car has a 195 degree thermostat and my normal temps are 200 to 205 degrees. I see 230 to 235 on really hot days with the A/C on. Pretty normal from what I seen in many places.
