The head of mine came off at less than 3000 RPM, a couple of hours into
a rebuild. A friend had it happen twice. Someone was kind enough to give
him a set of brand new Ford valves. He thought the first was just a fluke.
It wasn't.

If you look down at top of keepers they should not butt together.
If they do, then it has the multi-groove, loose-fit, keepers and likely
the original valves. This isn't 100% accurate as there are tight fit
aftermarket keepers for the stock multi-groove valves. Compressing
a retainer to expose the valve stem would show the grooves. Also,
replace the retainers as they are none too strong.

My intake valves had the Ford logo on them but you've got to remove
the heads to see.
