Sorry to interrupt here, but a friend is checking out an original
'72 454 SS Chevelle he just bought that is supposed to be numbers
matching. However, he has 781 heads with 75 date codes on them. Anyone
know the correct casting number for an LS5 365-horse cylinder head, or
a URL to a website for this?

Check out this site http://www.nastyz28.com/bbcmenu.html .I've got 781s
with big valves and have been ported and checked on a flow bench. They
don't work half bad on my 496.

That page answered the question. Rest of the site looks good, too. I
forwarded this to my friend. Thanks!!!
