Re: Best plugs..??
It depends on what you are going for. In my barn find Tudor, I have the original plugs (champions) that work just fine. In my truck, I have new champion "go plugs". In my tractor, I run the standard fomoco plugs for a's. All seem happy.

I use the 16y's. The work, cheap, and look beefier then the autolites. Are they better then the autolites, no. I just like the looks of them.

W-18
But only if: • you use 15/40 Rotella • you have blackwall tires • you have a 160° Thermostat • you have a 12v alternator • and an overdrive • A/C is optional

Re: Best plugs..??
The O'Reilly description stated a plug gap of 0.033" to 0.038". What do you use for Model A's? Isn't .018 to .022 recommended?

Re: Best plugs..??
Please disregard my earlier post, obviously I was thinking of points. However I am interested in what you use for spark plug gap if you run a high compression head.

Re: Best plugs..??
A good stock coil should fire the plugs fine with .035" gap, but many will cut back to .025" to .030" just because the higher compression takes more voltage to jump the same gap. The wider the gap, the harder the coil has to work, but it will more easily fire a lean mixture with the wider gap. I've never had any spark miss by using .035" on my stock head, and I'll probably try .030" gap on my 5.5 head when I install it.
