Valve Spring - Broken problem found

yellow rose said

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.

I was agreeing with you about the springs being junk....it was maybe my wording that seemed like the heads were junk as well......no problem, it's all good.
I honestly appreciate the candid feedback.....my feelings rarely get hurt, no worries there....lol....no need to beat around the bush.....junk is junk.

No question these heads have to be pulled and upgraded with some quality parts now, to get it back to a normal driver for now.
