I personally think Comp Cams would probably come up with any reason to make it not their fault. (disclaimer; I don't like them or their products).

I had 2 sets of their roller tappets fail on one dyno session. Looked like sub standard material and design to me. Sent them back they said it was detonation. My fault according to them.

8.9 to 1 compression, 36 degrees total advance, 93 octane fuel. There was no freaking detonation. But that is just me.

BTW Crane rollers doing just fine in same application. F comp cams.

The roller tips on the rocker arms flattened out as well......... I tend to believe they are right, valve trains don't just come apart after two hours..........


here's the spacers and stock afr springs this idiot used...........

This was a brand new set of AFR heads.........

yeah, my beef with comp cams doesn't negate the fact that you got screwed.

The minute the builder told you he was going to re-work the brand new AFR heads you should have ran down to his shade tree backyard and picked everything up. Sorry to hear of this mess you are in.
