Are the stock olds keeper angles 7deg or 10deg?

 

I believe they are 7 deg.

 

definitely 7 degree

 

The only factory 10 degree keeper I know of off the top of my head, was for a Buick engine. If you have a true Oldsmobile engine, like said above, they would be 7 degree keepers.
If you have a true Buick engine, it could be different.

The 10 degree keeper is like 2x thicker than the standard 7 degree, scrawney tiny, keeper. Hefty item, that many in the aftermarket like to use with monster valve spring pressure.
