Valve Spring - Broken problem found

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.


I don't think the heads are junk, just the spring.

When you see a spring fail like that, in an application such as yours, that's just a junk spring. I've done that to some very good springs, but that was at 8500 so it's a bit more acceptable. Not much, but a bit more. At least you can say at that RPM the spring has a short service life.

In your case, that spring should have went a 100k and never missed a beat.
