Hi Frank. Same thing, same bolts. I wasn't going to hammer the daylights out of them, took a drill press, protected threads, sanded them down (still have to hammer then in though, but they are snug). Brutal affair, then figuring out the torque will be (very) painful. I'd get something else in retrospect. See attached link where I got these down to size, but I'm still living the 20Nm+90 vs 55Nm. ARP it, I'm in canada (ARP to here 500$ Can delivered taxes in)and I had extra of the bolts you have, so I stuck with it, besides arp tech spec'd the bolts as I wrote in the attached link and they would not have been snug at minimum tolerance they can guarantee, those min tolerance bolts would have fallen through so he suggested I use the bolts I had, so it's up to you, you can call them yourself and see. Anyhow, looks like I'm going 20Nm+90, but I called Porsche today and they called back, saying 20Nm then 55Nm, just like the original spec, this crazy torque stuff will waste your time/energy/vacation. Unless you are retired or have months to kill or are a go-lucky sort of guy, get the arp and tell us how it went, it should work out just fine, it's just that the cost here and the uncertainty of receiving a min tolerance delivery from ARP and they would not cover me if that occured meant I had to stay the course.
