Re: flathead metalurgy Q..
Back in 54-55 I worked in old timers garage, had an old coal furnace, one of the guys was a stock car king, Ive watch him put the heads right on the hot coals, I don't know hot. then he would take 2 sticks brazz and melt it into the chambers then have the heads milled. He loved those 221 37 heads, he wound the hell out of those engines. Won a lot of races, the started running the Hudson 308. He had (Maine Hall of Fame), he died a few years ago at 85.. Walt
