Tightening rocker stand bolts on 356 - 912 heads

Post by Super90speedshop »

Just reassembling my 356 motor. The cylinder head bolts themselves are torqued to 22ibft. These special head bolt fixings are critically lengthen so as not to tear the oil sealing ring that's on them. The three rocker stand bolts then fasten into three of these special flanged cylinder head main fixings. But the specified fixing torque for the rocker stand bolts is 36ibft so you are tightening them at 36ibft into cylinder head bolts which are torqued at only 22ibft. Surely this will tend then to over-torque the main cylinder head bolts. Just wondered if anybody had been struck by the same observation and if they had come up with any reconciliation???
