Did small block 350 have spark plug wire towers/holders on both side originally from th factory in 1968? Just trying to find the correct way to seperate the wires.
Yes:
Driver's side -

Passenger side -

Spark plug towers were factory on 68 350s on both sides and used in conjunction with plastic plug separators that attached to the lower edge of the valve covers. These used the valve cover bolts to be held in place. If you have a brake booster the hole on the drivers side tower was used to hold the vacuum line form the booster to the intake manifold as well.
