Valve Spring - Broken problem found

Looks like number 2 exhaust. I'd pull every spring off and throw them in the garbage. There is no reason for a spring like that to fail like that.

Those are J U N K junk.

Ya, I am far from an engine master....I have done motor swaps/replaced heads/timing chains/hedders, etc. I know my way around an engine and not afraid to get at it with older cars that are simple......when i seen that spring, I thought it was odd, since it does a simple task and shouldn't break like that.......but I lack the knowledge and experience to know what is and isn't junk in a head....lol.
Thanks for your input calling them junk, it now leans me towards replacing the heads, getting rebuilt ones or getting these rebuilt with quality parts.
