Rory,
Don't forget the early 1969 production runs had the NASCAR based block and heads o-ring set up and the later ones and the '70's had the street engine o-rings which were reversed between the heads and the blocks on the T and S versions. Two guys here and them, one a Wimbledon (?) White with the track motor and the other a later Jade Green with the Street one. If memory serves me correctly the crank and rods were different as well when they rebuilt them.
