Chips are a flyin'! - Page 2 - ZR-1 Net Registry Forums

Gasket is good if it's OEM (or mine:wink) only saying that because those are the only ones I am certain that are made to spec. Others may be copied from gaskets.

In addition to port dia variance, there is core shift in the castings so ports often to not center in the gasket, as you have probably noticed.

It is a tedious job! My hat's off to you!

Got a long way to go yet, but making progress. Many thanks to Lee (LGAFF), Pete (Pete

) Locobob (Robert), flyn Ryan, AL, and Marc H for your suggestions and expertise and putting me on the "fast track" as far as learning curve goes. "The Brotherhood of the BEAST" on this site is terrific, and without them, I rather hesitate to think I would even consider tackling this one myself.

The SE-6 carbide bur suggestion turns out to be spot on. And the SE-5L6 w/ 6" shank should be fine as well. After an awkward start (with the wrong bur) I ended up with two perforations of the large radius in two plenum runners.

Switching to the suggested SE-6 and alternating between sanding and grinding has made things go 100% better. I did end up perforating the short radius on one more runner, but the plenum runners really look nice. The plenum is done, except for Al doing some of his welding magic to patch up the holes and a little re-grinding.

Now that I have the hang of it, its on to the IHs. Is it spring yet???

Hey Paul, wanna do mine next? LOL

Working on the IHs now. Easy does it. The project is starting to come together - still a long way off, but making progress.

Got the short Powersticks yesterday, and I ordered the SW X pipe Monday. It's gonna be a 3" (more or less) all the way. The Magnaflow mufflers neck down to 2-1/2" at the inlet, and splits into two (approx) 2" pipes - one to each of the twin tips. We'll see how that goes.

Back to "the grind"....
