LT1 Torque specs?
Finally finishing with the basement remodel after the big flood earlier this month.
Now getting ready to install the modified LT1 manifold onto my 91 L98.
What torque are the fuel rail to plenum bolts?
What torque are the manifold to head bolts? Should I use sealer on these bolts to prevent any coolant leaks?
Thanks - I have the 91 FSM but no info on the LT1s.

From the 96 FSM: Tighten the fuel rail bolts to 10 N.m (89 lb in) (Inch).
For the intake manifold, per the 96 FSM: On the 1st pass, tighten the bolts to 8 N.m (71 lb in)(Inch). On the second pass, tighten the bolts to 48 N.m (35 lb ft)(Foot).
The FSM does not call for any sealer on the bolts but I guess Teflon thread putty would not hurt. Would not use the Teflon tape though.
