Valve Keeper Degree?

TA says 11*, every single listing i can find either says 7 or 10 degree. Which is it?

I was using that stupid f*cking parts store valve spring tool and it exploded and shot my keeper into outer space. And, once again, parts stores don't stock them.

 

7 for mild street and stock spring pressure.
10 is more used with higher spring pressure.

 

Buick uses oddball 11 degree. Don't try to use anything else.

 

I found my stash of old keepers and retainers. REJOICE. PARTS STORES BE DAMNED.

 

"7 degree" keepers aren't exactly 7 degrees. They're somewhere between 7 and 8, but nobody lists them as anything other than 7 degrees. Except maybe Chrysler.

Probably the same with "10 degree" keepers.

Beyond that, if they're OEM Buick valves, they'll have goofy keepers to match the goofy groove in the valve stem--rounded instead of "square" cut.

 

You will have a hard time finding Buick locks at an auto part store. We're the only ones that make them anymore. We sell them to Pioneer, so it depends on who purchases and stock em from them.
