They have a large step-down right after the flange opening

Derr, I wonder then if they're even 1 3/4" after that? Was hoping he'd found some dirt cheap 1 3/4" primary 3" collector units. That is one area I'm definitely leaving some on the table with my dually.

Stepdown and flange measurements.

what's the brand and part number for those thick valve cover gaskets?

Spectre Performance 586.
I actually have them stacked with normal Felpro gaskets in order to clear the rocker arms.

Thanks! Headers look great too!

Ah broken exhaust studs. I have 3. They are at the very top of the LIST OF THINGS I'M GOING TO IGNORE.
Some if I ever get to doing headers I'll have to address it.

Those headers do look nice!

Y'all have gotten me extremely paranoid about my exhaust studs now. I was spraying them religiously with Kroil for a period of time but I haven't done it in about a year? I need to get my ass in gear and get my free headers cleaned up so I can install them.

Not sure if that's gonna help you? Mine was broken before I touched anything.

Fixing it was fun. And by fun, I mean it made me want to punch babies. And I like babies, at least the 3 of mine.

So I take it I should invest in some good EZ-Outs and plan for a day where I can lock myself away to avoid going on a rampage?
I don't THINK any of mine are broken? But there is occasionally an audible ticking when I first start the truck but seems to go away once it's heated up

The broken ones I have are easily evident by the spark plug heat shield dangling. If you don’t see them missing, you should be ok. Doesn’t seem like they break on extraction, just over time.
