AFR said these heads were two years old based on the serial number on the sticker. The springs did not have the colored ID stripe that their current springs are marked with. AFR switched spring manufacturers about that time, so maybe mine was an old set and maybe didn't get heat treated appropriately.

So a new set is going on and then we will see what happens.

Is this a hydraulic or solid cam?
