So with Vortec heads and TBI injection what spark plug gap do you guy's use?
I see Vortec head spark plugs like the AC-Delco R44LTS6 have a .060" plug gap but TBI head spark plugs have .035" gaps.
I'm assuming this is related to the ignition system, so if I'm using a TBI style ignition I should use the TBI plug gap on the plugs for Vortec heads?
I'm actually running an MSB billet TBI dizzy, Pertronix ignition coil and MSD leads.
I've got some weird knock count issues that I'm trying to figure out and I thought I'd try a different spark plug (currently running NGK BPR5EFS).
I've also just ordered some AC-Delco R43LTS6 plugs so I can try a slightly cooler plug.
