Thanks for all the replies,I ended up buying up several sets of the j12y non-resistor Champions.
What I've since learned is if your carbs are not dialed in,spark plugs don't mean jack.
I've been trying to do the six-pak on a budget approach and I've learned way more than I ever cared to know about them.No wonder many said they are troublesome,it's a pain in the butt just getting them off the manifold!

OMG.....you see the light.
Sorry but, I ran a 6pk setup with tons of problems, swithced to a 3310 carb eddy intake on my 383, ran better and stronger....plugs....never a lick of trouble with rj12yc's, but, i do run an accel coil....maybe the champs want more spark to stay clean as one post previously said about a higher resistance. good luck and just keep trying things to find what YOUR combo WANTS.
