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...

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.

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.
