I'm getting ready to convert my 1970 Cutlass S to an HEI setup. I've purchased a Pertronix Distributor (part number D1100) some Accel 8mm wires but I'm wondering which plugs I should be running with this setup? Should I be looking for a set for a 1975 or newer 350? Thanks for any help.

 

No because the stock plugs are set up for .080 gap and that's just ludicrous. .040-.045 is just fine with HEI.
