I just received my order from summit and the plug wires that I order are not 8.5mm cores. They shipped 8mm heli-cores. Will these work for TR ignition upgrade using MSD 6A. I know that the MSD instructions say 8.5mm but the last time I order the wires the guy from summit said he understood but got the order wrong. I hate to send these back a second time.

Thanks for the help. als.

Any of the Heil-Core wires are just fine...
Have them send you a credit for the differance.
Don't pay them for screwing up.
