Wrong how? Mislabeled/packaged incorrectly, bad temper/heat treat, joe schmoe installed go kart spring in pro stock engine?

one of my sets of heads came with the solid roller springs..... noticed one pair of heads had totally different springs then the other, we checked them and I had 290 seat and 720 open on port engines heads, forget the actual numbers for other engine but they were the 8002 springs I ordered....

Was this on the head that failed?

No, we know for sure the failure was stuck lifter, but still had other things to deal with like guides and now spring issue, like I said this has turned into a perfect storm of events, things most guys would not catch, I am not a rookie but also not stupid, I cant believe the springs are different.... I never noticed it...

i am suprised those springs did not colapse the lifters instantly on startup.

Me too... So crazy

tim,never buy a lottery ticket,they will call you and say you owe the winner his money.man you have bad luck.

You can clearly see the difference in springs when you are looking for it...

I am in NO WAY trying to bash afr or any person, not at all....

I am posting because you guys gotta look closer I guess at bolt on ready heads because although everyone's telling me I am the issue and there are tons of afr and other brands with no issues out there, it can happen is all I am saying, sorry guys pics don't lie, gauges don't lie... I got the one and only set or sets if issues, could have been a bad day for me I don't know but clearly I am saying check heads before bolting on simple as that.... Lesson learned .... The hard way... That's normal for
Me.

That's just scary..

I may not of read that you pinned it to a lifter being stuck. I may be reading it wrong but the rookie and the stupid I am not calling just want to see why it failed and learn something.
