Retorqued my heads, do you think it's okay
Drivers side head was leakin coolant onto my headers when heated and under pressure. I just retorqued both heads, the drivers side was only about 5 ftlbs off. Using commetics with copper spray BTW. Do you guys think that 5ftlbs is enough to allow a leak or should I look elsewhere? They were not leaking untill I put a few miles on it. I don't want to put everything back together unless I'm fairly sure that It won't leak again.

Assuming you're running aftermarket head bolts that aren't torque-to-yield design, then I'd say no issue...as long as you followed the recommended torquing sequence.
It used to be common practice with engines to re-torque the head bolts after a heat cycle or two.
You might want to add a pellet or two of cooling system sealant for good measure, but if it still leaks after this you'll be removing the head(s).

Leaking gaskets, Ouch. I try to avoid sealers in the radiator because they can plug up other things. Retorque was a common practice with high compression small blocks. As the above post said, if you are using an aftermarket bolt, that should work. If you are re-using GM bolts all bets are off.
BTW, do you have a good torque wrench, I had a leak and found that the old low budget torque wrench was off by 15%.
