I too live in PA and I get soft or pure lead from cabelas, they sell 4lb ingots that melt and pour easily. But even if you are using tire weights or something similar it can still be done. I use a small propane torch and while my lead is melting I heat my mold with it, about 2 min. with the torch and the mold is plenty hot. Next thing I do is pour about 5 or 6 blanks without hooks to see how they come out and if all is well I add the hook. After I add the hook I'll give it a 5 sec. shot with the torch to heat the hook a little and then close the mold and pour. I heat the hooks for the first few jigs then after that I just put the hook in and close the mold for a few seconds and no incomplete pours. If you're like me, and are pouring from a hand held ladle, you have to do it pretty quick, it takes some practice but you'll get the hang of it in no time.
