you've gotta be patient, Capt...
and I owe you a Thanks..
... I was at the Autofest in Nashville last Saturday, and each time I saw small block '69 heads, I stopped and inquired about the numbers.. (thinking of your 041!)... well, I didn't find your head, BUT.. in my search, I accidentally came across a matched set of 186 heads which are *perfect* for replacing the heads I sold off my Z28 back in the seventies!! .. Now I'm just hoping they turn out to be good and rebuildable..
I've been looking for good dates for 186 so long, I'd given up and *settled* on some not quite as good, and I probably wouldn't have bothered checking numbers on the heads had I not been thinking about your need for an 041..
