if you went by tsrm spec which is 58ft/lb thats where you went wrong you should have done 80-90ft/lb and went over it twice

Read any thread about a bhg and you will know. Factory torque specs (which are the ones in the repair manuals) on the head are way too low...

When you replaced your head gasket did you use an O.E. one with new O.E. head bolts? Or did you use a metal head gasket with ARP head bolts or studs? If you used O.E. bolts/gasket, it should be torqued higher, but not to 80 or 90. Those bolts won't hold up that high. Check bhg threads for what others torqued their head bolts to. If you went with the ARP/metal head gasket then you should take it up to 80-90 ft./lbs

This whole head gasket issue is the most common MKIII issue with the 7M engines, and people are writing about it all the time. Do some browsing around this forum and read bhg threads. This torque issue is in every one of them.

I used ARP studs.
Torqued them to 85lbs in 5 passes.

HKS stopper 2.mm mhg.

The mhg alone was 350$

keep in mind that they came up with those specs 20 years ago and they found out it was way too low a couple thousand miles later
