New motor with LOTS OF NOISE

[middleagecrisis]

Sounds like valvetrain noise and some exhaust leaks to me.

From the description I actually expected it to be worse.

I consider the one in the link to be the benchmark for HR lifter noise.

They actually dyno tested this one making that kind of racket!!

Oh my god! I sure wouldn’t have posted a video of that.

Sounds like valve train not happy. Pop the cover.

Without knowing what cam profile and lifters he's using it's hard to say.
Rhoads lifters in particular are noisy, sound like a sewing machine.

How would you find the dead cylinder? As 67Dart says above, you damn sure don’t want to pull the boot off the plug.

If a paper clip kills your 200 dollar wires you paid about 180 more than they are worth.

You can insert as many paper clips and nails or whatever you want into your wires. I prefer to not do that to mine.
I’d use an infrared thermometer and check the temp on the header tube
