I just installed my 1725cc engine and am on the first 300-mile leg of the break-in period. My question is the torque speck for the final 700-mile leg of the break-in period. The Workshop Manual spec calls for torquing the head to 48 ft/lbs. However, the Roots Bulletin 68/3 on 28 Feb 19689 reduced this figure to 45 ft/lbs. My problem is I don't recall which spec I used when I initially torqued my head. In retrospect, I probably used the 48 ft/lbs spec as my manual was close at hand at the time. Assuming I use the original spec, is there a problem if I torque the head to the 45 ft/lbs spec when I torque the head for the final 700 miles? Or should I torque the head to the older 48 ft/lbs spec?
