500EFI - .040 Vs .035 Plug Gap

I Put New Extended Tip Plugs (R43TS VS R43T) And Had A Brain Fart, Gapped The Plugs At .040 Instead Of .035. Do You Think It Will Be Fine Or Should I Pull All The Plugs And Regap. Thanks For All Your Help.

you will be ok at .040 where people get into trouble is opening the gap up to try and pick up a few more h.p.'s and they have old spark plug wires and they start misfiring. the stock coil has enough voltage to fire a wider gap than stock.
my 2 cents anyway!!!:D

They should be fine for a while. Eventually they will burn the tips harder and you'll have to change the plugs sooner than before.
