It's about time to change the plugs in my 56 Victoria. It's a 312 with c-4. Car runs very well and uses no oil. Very limited time on the road as most of it's use is to local car shows 50 one way miles or less. There are times when it never truly warms up. Champion F-14Y are in it now. I'm wondering if that's still a good choice, is there something better you guys would recommend? Concourse Parts lists a BF-82. Dennis Carpenter lists two, both just described as Champion 18MM. Thanks
