The AR looks to be a recessed electrode and that is a total different animal. I use the AR 23 or AR 24Just to show a difference;
Same engine, same tune, same time, same gap, left vs right bank

It may be obvious, but that is exactly what I was trying to show.With the AR plug it looks as though it runs cooler than the delco. . . . . . .
The ONE day I ran E3's in my car at the track it ran like total crap. Yanked them out and put the R43TS's back in and it ran like it always did, which is great. Never again.
DaveNGK YR-5's here (they are a non -projected tip) ....less likely for detonation .
Have'em gapped at .030
I just got some delcos from earl trying to stay OG
we'll see how the delcos do firstOh damn.... Funny story...
Earl also has NGKs (just like in Earl's personal GN. AND 72 Dodge van, TVR, S10 Blazer and 11 motorcycles).
The NGKs don't have ''Made in China'' on the box. (yet I've sold ZERO sets).
All jokes aside, Grass Doctor, if the Delcos you got from me are still new, feel free to mail 'em back and I'll send you some NGKs.
Earl, what say you about ngk bkr7e ? They are called v power with a small groove in the tip. Seem to fit nicely where a gasket plug is used and aren't hard to find in a pinch.Oh damn.... Funny story...

I run 28-30 psi on Champion aluminum heads, 93 octane and Alky. I will never use an extended tip plug for fear of pre ignition.
NGK R5671A-8 is what goes in mine at .024 gap.

I have used the AR3933 before. I just seem to get better performance from the ngkGood plugs. Give the Autolite Racing 3934 or 3933 a shot. Same as the NGK you run but a shorter strap for even more pre ignitions prevention. They come out the box gapped at .024.

So...I have a dumb question. I picked up a set of NKG UR5's (2771) based upon many of your suggestions. According to the auto part sites (Autozone, etc) these do not fit the car. I'm assuming we are good to go and I can ignore that? I just want to make 100% sure before I install them.
