I've checked out some other pages on this and I can't seem to get a clear answer to this. ARP doesn't technically sell a head stud kit designed for the 420a in the Mitsubishi, and the issue is that the four outer studs are shorter than the inner 6, the kit from what I can see is 10 studs all the same length. I emailed ARP to see what I can work out and I'm waiting on a response, but most of what I have to work with is stock photos, so they didn't get me anywhere. And that doesn't help with exhaust/intake studs if they aren't included with the kit either because I've seen some that look like they're in it and some where they aren't. So what's the answer, is the kit right or do I have to order the studs all separate to spec? Its be great if someone had this kit and took some pics, in case it's just a problem with the stock photo bs. The part number I looked up is 141-4202.
