What is the expected change in gapping from .045 to .030?
Should this be considered significant to engine operation or a minor detail?
Running AC 45S gapped .045 on my 68 455 but noticed some erosion on the insulator after only 30 miles. Actually looked melted.

melting insulator is a very lean condition.
If you are using HEI then larger gap ok.
