Bruce and Henry,

Thanks so much for your rapid response. Now I at least have 2 different back-up methods by which to proceed....much appreciated!

Reason behind replacing all 24 studs was due to the advice of an ex-Porsche R&D executive engineer (and friend). He states that even though the studs are not torque-to-yield fasteners, they are torqued close to yield and after 23 years of many thermal cycles, it is prudent to replace them all. I realize the subject is somewhat controversial, but I thought while the engine was disassembled to this point, the $330.00 cost for 24 new steel studs was good insurance money. My biggest nightmare would be to have a stud break on my freshened-up engine.
