WHAT do you do?

I rebuilt a 5.9 engine.
Bored 030 , new pistons, rings.
Polished crank, w new bearings.
New cam, lifters, etc. etc.
after going thru 2 sets of cracked heads, …. bought a pair from big name head Re-Man-fer.
Cool…
Everything is great. Until 100 miles into driving,
Valve spring breaks, drops valve,
Destroys piston, twists a rod, cracks cylinder wall, and all my effort has been reset.

Seems like I am getting SOME compensation from them. (sent a new set of heads right out).
Also Just got new gaskets, rod, 1 piston (that is a mis-match from the others) - and a “credit”???
My pistons are only sold in a set of 8.
When do I just bend over, wipe the tears and declare the screwing I am getting doesn’t hurt all that much?
