The $100 exhaust studs fix a different problem than vibration.

That's a stretch since we have documented instances of stuff still vibrating, cracking, and backing out on balanced BP's.

But I'd agree it would likely help

I did not balance my rotating assembly. Makes chicks super horny. Vibrates like a boss. I did balance all of the rods and pistons seperately.

Then again, I don't have anything to compare it to.

Balance it. It's the foundation.

This is all pointless if my valve cover isn't polished. That is of highest importance.

I guess my build will be screwed then.
I am just getting rods, rings and swapped bearings around to get the right clearances. All that with a quick bottle brush hone.
Maybe a hot tank and a couple of surfaces.

Speak for yourself! Mine is within 1/2 gram and motor mounts still backed out of block. Thread locker is still my friend.

I thread lock almost everything to help reduce this.

I've done this a few times and ran 20-28 PSI on them, it can work. If you run high boost, don't let it detonate on stock pistons they don't like that.

Ugh, somehow bought the wrong fuel rail adapter from the UK. So now I have to wait another forever for it to come in. And maybe they will take this one back.

Sometimes I wonder how I've made it this far in life.

Same. But then I remember, I have not made it far at all.

Let me know when you're assembling, I could try to head over for an hour or two with my snap-on digital torque wrench. Mains and rods aren't something you wanna use a click type craftsman with. Letty can entertain Hailey.

I bought a bunch of beam type. Just to be sure. May take you up on that. James and I are actually going to be doing side by side builds.
