New head gasket leaking.What did I do wrong

I had my 202 cast iron heads redone on my 350 chev I put every thing back together and after I drove the car for a while when I got home I was checking every thing out and I see that I have a coolent leak on both sides of my heads driverside and passenger side it seems to be comning from one of the head bolts it is just a weep not a steady flow.I drained all the coolent from the block and pulled the 2 head bolts cleaned them and put them back in re-tork took the car out for a nother drive same leak.Do I have to take the heads off and start all over or should I just wait to see if it gets worse.The car is only driven to car shows and only gets about 2000 miles on it a year.

I agree, if you dont want to pull the heads again, take those bolts out, thread sealer, or teflon tape, retorque those two bolts and the 4 or so bolts around them. If it still leaks, I'd say pull the heads, get new gaskets and try again. Problems always get worse, never better.

Pull the bolts and clean them real good with lacquer thinner or gas. Dry them good and put some Permatex #2 on them. Don't be stingy either. Put them back in and re-torque, should be fine.
