If you install CJ size valves in a 390 / 352 the edge of the intake valve hits the relief on some of the stock Ford pistons. Don't know about the Silv - O - Lites but would check any piston of any brand.

With a bunch of bent pushrods and one broken valve and one broken piston some assembly problems existed for sure.
