Hello, I have a question regarding my spark plug choice .
I have a 400! B block with Ross pistons small dish but set at zero deck height.
Running Stealth 440 heads .
Engine will be run with a six pack and a small roller cam . 2836 roller hydraulic from Hughs engines 525 lift .
Thinking about Running autolite 3924 .
Mainly because I have a new set on the shell from about ten years ago . Will these plugs be fine or should I use a colder plug?
