Just something to consider.
That was the answer to my own question....in the olden days Tom, it was cast iron to cast iron...in today's builds, it is aluminum to aluminum....softer metals if you will. You can't torque aluminum like you can a cast iron block...and aluminum is finicky about what it likes to mate to...cork is cheap, as I was told by Rudy, and use a new set each time....
