OH is correct, with E heads and 1 and 7/8 Comps (not Super Comps)I had to very slightly ding 2 tubes on the passenger's side. No big deal, I've had the same plug wires since 2001 or so and have never burned a boot.

Will be switching to 2" Super Comps shortly, Looks like some mild dinging of #1 is all that will be needed.
