With all due respect I disagree partially though I agree fully with the surface mating to the nut being the key part. I applied a very thin coat to all thread as well as a liberal amount to the nut surface.
The bottom-side of threads themselves are physically grinding as the nut is working it's way down down them thus they'd be affected by friction as well though perhaps not as directly I wouldn't advise one to be careless with application to the threads just because the nut head is more important.
Am I reading your signature correctly? You're making 740whp on stock compression? Even with E85, damn impressive. Someone got done arguing with me a couple weeks ago about how it's IMPOSSIBLE to have even 8psi on stock compression. I had to giggle.

I didn't mean it's not important to also get some molylube on the thread, just that the mating surfaces of the nuts and washers is the most important.
I'm actually now on 34 psi and making around 800 whp. I was on 29.6 psi when we made 741 whp.

Wow.... regretting my 9:1 choice then. LOL Except he's on E85 which I'm not willing to do.
Still I should have probably gone 9.5:1, I had a feeling at that moment. We'll see what happens though.
