As Keith said, if it is not puking out coolant, then it is probably fine.

But if you are still worried, then put a temporary mechanical temp gauge on it as Keith suggested. Put a new radiator cap on it rated at least at 14PSI. Any temp below 220F is fine.

Last year my restored 79 TA got caught in traffic in 114F crawling over Hoover Dam and the temp gauge hit 255F. It survived just fine although it would ping under load due to today's lousy gas until the temp cooled back down to 220F.

As far as the rough running is concerned, I agree with Keith that it is probably marginal vapor lock. I have an aux electric fuel pump on my 55 Pat and 79 TA and I don't experience vapor lock anymore even at crawling speed at 110F.
