found this on a Comp Cams description:
..is this required when doin an OE PI cam?
For 1999 and later performance improvements heads. Can also be used in 1998 and earlier heads with retainer to guide clearance modifications and Comp Cams valve springs.

When we did the PI cam/intake swap on my friend's 96 Mustang GT we kept his original valve springs. I am not sure how much different the truck valve springs are but I would think you wouldn't have a problem.

gotcha. I have been considering this swap on my '97. I will be pulling the drivetrain at some point in the near future and going through it. I get a suspicious "rattle" at start up and have thought it was a chain issue. I now have 220k miles and its time. I don't burn any oil, and no smoke, but I have considered resealing the motor and doing the PI swap. Would it pose problems on an original bottom end? I could perceive bottom end issues if the top end is refreshed, but I understand the short-block to be pretty robust and I have taken really good care of this one I have(synthetic every 5k miles, Healthy tune up every 30k). I just want to reseal some pesky leaks and get to the bottom of the rattling issue before it lunches itself. Thoughts?

That is great info JL. I think that echos what you have already stated here in this thread if only I were a little more attentive when reading. That really answers a lot about what I want to do. I will keep an eye on this thread and try not to make everybody repeat themselves. Thanks for your patients. Oh... and thanks for the great info.

I have another question. I hope it is not terribly off-topic, it may be pertinent here, but why is this exhaust for '00-'03 applications
