The marks you are referring to are meant to be there. These are timing marks that are also visible on the OEM pulley. They are used for timing the engine should you need to replace a timing belt, rebuild your engine, etc. at some point in the future. High quality pulleys have these, and cheapo "copy-cat" pulleys do not!One question I have about the pulley is that on the lip of the idler pulley there seems to be 2 sets of about 5 very (and I mean very) small notches. Both sets are evenly spaced almost like it was grabbed with the teeth of a vice grip or tool of some sort, which I know is not possible based on the location. I haven't looked at the stock one yet so I don't know if this is meant for something or if not is this something I should be worried about? Aesthetically, I'm fairly sure you won't be able to see it so if its not supposed to be there and won't hurt anything I don't care.
Any idea?
Just plain AWESOME!!! Simple install, quick and easy. Threw me a little since the crank pulley didnt have teeth like the stock one but a couple of taps with a rubber mallet and it went on without a problem. Also a little disappointed in Ingalls not being able to get the redesign correct to accommodate the new Idler Pulley, but 5 mins with an angle grinder fixed that.The marks you are referring to are meant to be there.

Good luck and be sure to post a review here in this thread after your install.

Well I hear them on high rpms because I have stock intake/exhaust. It's not wow I hear them, but with the windows up and stereo off ya I can hear a very slight metalic noise which I assume is completely normal because of the different design of the idler pulley? I can confirm what everyone else said about these pulleys it really smooth things out and the gain is on the entire rpm band. Nothing crazy, but a gain that is noticeable and I like it a lot. IMO these pulleys are the perfect mod for those who don't want to modify anything else and will sure help other mods also.Not sure what you mean. I've never heard the pulleys. You are actually able to hear the pulleys while driving at high RPMs? I'm not talking about having someone reving it in neutral while you have your head in the engine bay. There are a lot of components under the hood that make various sounds and I would think something like the alternator would be much louder than the belt riding across the pulleys, especially with the "soft" belts that are used now days.
