Ferrea makes a bunch of different types of valves: the 5000 Series High
Performance valves, the 6000 Series Competition valves, and the 1000
Series Competition Plus valves, along with a number of specialty valves.
The 5000 series are inexpensive street performance valves meant for flat
tappet hydraulic and milder solid lifter applications. They are not meant
for race type roller cams. My friend was using the 5000 series in drag race
motor with solid roller cam and popped the head off. He was using the wrong
valve for the application. He switched to the 6000 series competition valves
which are meant for roller cam useage and has had no further problems.
I'm not aware of the circumstances surrounding the second failure. I was
contacted by a Pantera owner who had one fail on him. As I recall, it was
a flat tappet cam street type motor the owner used for track days and the
failure occurred while idling in the pits.

Sounds good. BTW, I made a new photo album on my website with pictures of
351C EFI intakes:

It has some of the pictures you've sent previously.
