okokok..... I'm going to be that guy before you bring the block in for an inspection.
What is the condition of:
Coolant cap?
Thermostat?
Is there proper ducting from the intercooler to the rad?
Have you flushed the coolant system?
When it was all put together, was the system bled properly?
And lastly, what was the condition of the coolant when you drained it?

Lets get to the bottom of this, because I doubt you're overheating because of something going wrong in the block.
