Question 383 head bolt torque specs?????

383 motor with 906 heads. New heads at the end of last summer and the snow came before I finished. I have it torqued down but I'm about to break it in and I can't find the friggn shop manual....hate when that happens.


What are the torque specs for the heads and rocker arms? Once it runs a bit I want to recheck it..........

i have a 71 383 and i use the 346 heads , but i think the torque values were around the same. i torqued mine to 75 lbs in three steps. 30 1st, then 50 then the final one. as for the rocker shaft i used 30 lbs on those . this was from a 68 shop manual. good luck

The engine book (M-P Engines) shows 70 and 25 for heads and rocker shaft hold downs. Always do the big numbers in increments.
