I gapped my plugs to .050 and it's fine. As long as your spark system is up to it, (I'm assuming yours is the Duraspark since you have the same car as I do, which in that case it certainly is) you'll have better spark with a bigger gap.

Should be within specs, but its not the end of the world. Might run a little better gapped correctly but you're not gonna blow anything up.86 Lincoln Town Car (Galactica).

Gap em at .050 and install yourself a hotter coil,You will notice a nice increase in power and throttle responce in the upper rpms.Comment

I was meaning to ask about the coil at some point. Things work pretty good gapped at .050 but I was planning on pulling the plugs just to check the new set anyway so Ill prolly end up regapping them. Thanks.

I have heard that some power increase can be made with indexing the spark plug with the electrode pointed up towards the valves....1987 MGM 126K 2" True Duel flowmaster 40's 3" tipped exhuast, Tinted 20% all way round, individual bank A/F guages, tach.

A 89 and a 91 doesn't have a Duraspark ignition system. It would have a TFI distributor/module.Comment
