88 150 Head Torque

[chadbenton]

I am fixing to put the heads back on my 150 and my manual says 12.5 lbs. for a 74 degree block. I am sure that is the correct block but curious about the low torque spec., is it correct.

1988 engines were all 60 degree blocks....

Look here for the torque specs....
