dang! gonna hafta start using the glasses more blush that one looked too much like rotten plugs I've seen ... sure don't recall a casting like that on the 235 blocks I've dealt with, including the 57 I replaced the plugs on a few years ago .... but thinkin about that one, maybe because it was Canadian made? I'll hafta investigate

I guess mbt knows what to look for now!
