I run a set on a 496. Great head. Lots of folks run "out of the box" but a once over before use is a good idea. Check guide fit and upgrade to 10 degree locks and retainers if using a larger cam.



Both of mine were put on right out of the box with no issues, small block and BB heads. They are street cars, not race cars.

If I was building a race engine then yes I would take them apart first, but I would probably be running different heads.
