Hi im looking to put a set of headers and a cam in my 01 4.8. Any idea what type I should go with. Longtube or shortube. I dont know much about either one but I like the way it sounds with them. Right now I have a K & N air intake with dual exhaust and a hypertech max energy programmer.
And as for the cam I was looking at a 222/224 .568/.571 like casey.shoemake has in his truck. But is there anything else I would need to change while I was at it like springs, retainers, locks?

This is casey.shoemake truck with a 4.8 cam and headers.
