Higher compression leads to detonation. These engines were set up for 8.0 compression ratio stock. Aftermarket high-compression pistons increase chances of detonation.
I'm up at 9.50-10.00 now not to mention all the port work.
Boring results in the same as milling the heads. Compression will rise. That is why head gasket shims are made.
I never had knock until I had the engine rebuilt. Higher compression pistons may have contributed.
Shimming the head gaskets helps. (I missed this one).
Good write-up on the fuel Rich....did you get my PM?
