Got a 87 Monte Carlo ss chevy 350 small block first of all I brought the car pretty much how it is 350 with edelbrock torker 2 intake i believe edelbrock 600 carb got hooker headers and I believe thats only performance mods done to it now the motor runs hot not just sometime but everytime i drive the car now when i got it it had no thermostat in it (back in the summer) so i put new one in 195 degree failsafe with the reusuable gasket soon as I installed thermostat car starts running hot and yes its installed correctly and is functional been tested my coolant in radiator was a orange looking color but mostly green so i drained it 3 or 4 times checked it and no water in oil or anything somebody told me i maybe have bad water pump or intake gasket leak but i dont really think its either those im thinking heads are messed up they are the 882 heads so im ready to pull them anyway just figured id throw this out there see if anyone can help me fix this overheating please everyone chime in...thanks
