273 commando cylinder head bolt torque specs ? same as 340 ?

My 1121s @11.3 Scr, were almost into the valley by the end of the first summer. IMO
the 1121s need a rougher deck finish to hang on to them harder.

I caught the slide on the First of 6 teardowns. and that was with ARP Bolts, torqued to 105.
I swapped to the bulletproof 039 FelPros, and ran 10.7Scr for the next couple of years. I reused the FelPros every time at Q= 039.
When that cam dropped lobes, the next bigger cam had a soft bottom end, so I took it apart and re-decked it for a Q of 032, Scr of 10.95 (that wasn't enough to satisfy my hunger for a bottom end, but was a good start.)
At the next teardown, the gaskets were still looking good, so I reused them. At the last inspection, in 2004/05, everything inside the engine was surviving, so I gave her a treat with brand new 039 FelPros.
