Did I toast my 340?

Cruised Woodward Wed nite and the Demon overheated in the parking lot. Got it home, changed thermostat, gasket, rtv, added better hose clamps and done for the nite. Engine has run hot for 3-4 years but not on the gauge. Went to start it this morning, it cranked but didn't start; floored it 4 or 5 times and got it started. Went around the block, popped the hood and there's a mix of oil and antifreeze on the intake next to the crossover opening, see pic. Did I blow an intake gasket because it's so hot? If I drive it tomorrow, could this toast the engine? 2cents please. 340 Intake.JPG
