I recommend installing the followers after the cam is tight, but have never heard any different. Wow. Just wow. Some one got screwed.

There is definately something amiss in that head. i would take it to a "professional" and see what they could find as to a cause. Sorry to hear that though.

Thanks for the reply,this company i bought these heads from are supposed to be professionals,somebody dropped the ball and from what im being told it sure wasnt me.
All this damage is being blamed on a bad spring which cant see how,the valvetrain is completly in tack and in fact this company wants to reuse the valve again?
I just dont think i should pay for something that wasnt my fault!

The valve springs are incapable of creating this problem unless the incorrect springs were installed. Even if they were incorrect, i'm not sure that something else in the valvetrain wouldn't have broken before the camshaft seized, not to mention the valve springs would have caused the camshaft to immediately seize rather than seizing 1500mi into useage.

There is a tremendous amount of force necessary to stop a rotating object like that.

Again, installing the camshaft with improper torquing should have seized the cam immediately, not 1500mi later. I agree that an oiling issue would be more likely, but even so, 1500mi is more than I would have expected there, too. I suppose a cam that was improperly installed resulting in a bend could tend to bend further over time, finally resulting in a seize.

Even though the aftermarket parts do not necessarily come with a warranty, the engine builder is most definitely feeding you a line of crap, and they should stand behind the (faulty in this case) work they performed.

The engine builder or the company i bought the heads from

[Unit 5302]

The head builder (not engine builder) They installed the camshafts, and they should have found any problems at that point. If a valve spring was a problem, they should have seen it right then, but like most people are telling you, it's not a valve spring. It's unlikely that any parts caused the issue as the parts should have been checked when they were put together.

Sorry, I didn't read the linked thread quite well enough.

No problem i got a little confused there, but yes they should have checked everything before they sent the heads out to me thats what i payed for,i shouldnt have to check a well known companys work especially with there reputation
