The 1969 L-46 used cast aluminum valve covers that were first used for 1969 Corvettes with L-46 and 1969 Camaro Z-28s. These were the aluminum covers with provisions for the PCV system. One side had an emblem with the crossed-flags logo and the other side cover had provisions for a twist-on oil filler cap. The 1969 valve covers also had NO drippers on the inside, upper surface as did 70+ valve covers of the same style. The 1969 covers were more-or-less an "as-cast" finish and were not polished.

Tom,
While most 1969 to 1972 Corvette SB with aluminum valve covers had fasteners with the M headmark, not all did. Unless your bolts are chrome plated, or otherwise have some indication that they have been replaced, don't worry about the headmark.

If you want to buy the bolts with the M headmark, Paragon carries them. I just bought a set from them at the Florida Winter Meet.
