Well I got the ebay headers installed at the same time, so the car is ear bleedingly loud.

So loud, that I can't drive it yet until I get a stock exhaust so the cops don't rape me, so no review yet =(

Got out for about 30 minutes today. Went over the cam one more time with the pad, then I started wetsanding. Used WD40 and 600 grit. Made one pass over the lobes of the exhaust cam. Took a few pics, but I can't find a cable to transfer them! I'll put them up in a while. I'll make one more pass over the lobes and then start doing the journals.

I polished them. 600 grit wetsanding is just to smooth them out. I've got a feeling the person who told me to do it knows a bit more about the subject than you

Honestly, what do you think a few wipes of wetsanding and gobs of WD40 are going to do? It's really just to clean up the surfaces. The cams have been though a lot

I had the same suggestion when talking to my engine specialist as one of my lobes has some minor dents in it. He said he can't sand them smoother, but he'll try and polish them away with 2000 paper if at all, as he doesn't want to attack the hardened surface too much.
The only thing that could really happen, he says, is that the hydraulic valve lifter gets worn out faster. I took his word for it...

You'll be fine. Take a guess what happens to the cams in a car that's sitting a while in a humid environment? I can tell you that they ain't pretty but people just start the car up anyway and everything is fine. Nobody worries about it because it's all covered up. Out of sight, out of mind.

Which are they?

I sold the 264/248 out of my motor before selling the actual motor. With nothing but AA headers and those I was making +30whp over stock

Can't wait to see how it all turns out. I've been trying to get back into an E46 for a while, and it isn't looking so super quite yet, but I pretty much already have it all built out with mods I want in my head, and cams are on that list. Be good to see how they help another North Texan, lol. Where are you going to get the 3er dyno'd?

Jotech is my closest option. I'll probably go there.

Good deal. I've never been to Jotech, but a few of my buddies have and have nothing but good things to say.

I bought some parts there when I had my Talon. Not always the best pricing, but they're a nice shop. They told me they'd cut me a small deal on doing 2 sessions, so that's good. I'll post up before I go, if you can come out, cool!

3 Quick Pics, just to show progress. This is from Saturday:





I got out this morning and finished the journals. Got 98% of any discololoration off with VERY light pressure. I also managed to use a little paper and a dental pick to get all the rust/debris out of the splined shaft. I was worried about that, as I didn't want to take it off to clean it (so I can avoid having to source the helix tool to align it again). I'm considering this cam finished. I pulled the intake cam out and sprayed it down with WD40 and wrapped it in plastic to soak today. I'll get started on it in the morning.

Cams look good all cleaned up. I'll try to make it out there when you head out to put it on the rollers!

The cam locking tool is around $100 on Ebay. The Vanos tools for timing around around $300 nowadays.
