Message	thread shear calculations are not too difficult :) 1.5x length to diameter is a general engineering rule of thumb, yes. That also generally includes a 2x safety factor (another engineering guideline) IMO you have plenty of thread left to install the head. As long as the threads are clean and the bolt threads in freely (so you can get the proper torque). The proper way would be to install a thread insert (heli-coil, keensert, etc) ------------------------------------------------------------------ 1992 300ZX NA 5 Sp (Dead) 1990 300ZX NA Auto 2+2 (Dead) 1990 300ZX TT 5 Sp (Stock Turbos) (Est. 400 HP) 1990 300ZX TT 5 Sp (GT600R) (Est. 600 HP) 2004 G35 Sport 6MT (DD) 2008 Honda Civic (DD) 1969 Chevy C10 (Toy) 1969 Chevelle (Toy)
