Consider a roller valvetrain.

When considering the cost, consider how much it would be be worth to you to not have this happen again. All that metal should be cleaned out of the engine at a minimum; and the metal probably has trashed your machine work and bearings if it ran for any length of time. Ugly failure mode.

Another option is the new radius bottom composite lifters. Shubeck makes them. Also not cheap, but a completely different game in regard to wear.
