this is the crux of it. the BENZ bolts would seem to take a lot less time to implement. I do have a bit of time pressure here unfortunately. but not a TON.

i'm not finding much detail on the Mercedes solution though. among other things... which bolts to use and obviously a verified TTY method. i mean, if you are stretching those bolts to spec, it's going to take a good bit more torque than the stock setup. now you've got two bolts clamping harder than the others. i was originally thinking just use the MB bolts in the repair holes but that might be a bad idea. would probably need to do all of them. so the TTY issue might be a deal breaker in that it takes as much time as timeserting 3 or 4.

so...i suppose the next step is to torque those head bolts again tonight. 40NM + eyeball 90 + eyeball 90. I know i am missing a washer btw...good catch. it disappeared somewhere under the car. I'll find it.

after that, lift the head off and check block and head for warpage. i think this budget is only gonna work out if my existing head is repairable and i can get it skimmed and tested for $200-$300, which i THINK i can. i know i can prob find a junker head for cheap and put all my parts on it but i've rebuilt a 12 valve M20 head before and that's no fun at all.

btw oldskewel, i tried to PM you yesterday to ask you some questions about your experience (namely, re-timing the cams/vanos) but your mailbox is apparently full! i'd love to hit you up with some questions.
