Yep, 60679. I bought them in about 2003-4 to do this build, but put them on the back burner due to time working on the oil rigs. But now I'm ready- all I need are 3/8" custom length pushrods (Smith Brothers?), new deeper front sump oil pan and a water pump. I happened to run into a test stand for the break-in and tuning. Couldn't have been luckier. Also, do you know where I can get cast aluminium valve covers, lower than Ford Racing covers, that will clear roller rockers?
