I have an assortment of exhaust manifold bolts. Some have a head without a washer that came off a 65 289. The bolts had the locking tab on each pair. I also have bolts that have a washer on them. The washer must have been threaded on the bolt. The locking tab would not work with the washer on the bolt. Are these bolt styles different years?

The bolts with locking straps were used on 65-66's up to about 12/65. They were then changed to the Ramp-Loc® design which did away with the lock straps.
