1969 BB Exhaust Manifold bolts

Did 68 big blocks also have the different style of bolts?Were french locks used in 68?Also if you had AIR injection did they use the french locks?The picture of the low mile Chevelle with AIR does not have french locks.

Sorry.The low mile chevelle I am referring to is from the "correct engine paint suggestions" subject.

I have two sets of 842's and the only Helicoils are the rocker stud bosses.
