Educate me a little on performance! Warning: Long post - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey, I know I'm not working on a '67-72 anymore, so forgive me please, but I knew this forum would get more views! Now I've worked on many a smallblocks, never necessarily in depth, like troubleshooting, for the most part, whenever I've bought a truck that sat for 5-11 years(which I have) I always just threw a tune up at it, some fuel a hot spark and off she went, But I've never had enough money to put headers or a cam or anything like that. Now that I'm in the Marine Corps, I got a decent check coming every month, and after I pay off a daggon ring I bought for my girl, I'm gonna try to throw some performance parts at an '86 GMC I bought off a board member, but what I'm looking to find out is what are really good things to buy for making power!!!!!!
I'm looking at something between shortie headers or long tubes? I know long tubes hand down really low, and I dont like that, just cuz I like ground clearance, even if the truck aint gonna be sitting 2 inches off the deck. Now which headers are better for a truck for performance? I'd like to tear ass in this little truck, so that is my intention, but I dont wanna go too radical as to kill me in gas mileage!

This is the truck I'm starting with, so it'll need new manifolds because it's using a '73 motor and the dipstick location is on the wrong side, so why not just buy headers.
I'm also looking to maybe get a cam for it, some people say they like their RV cams, but I have no idea what cam is what, I realize somewhat what life and duration are, but I have no idea what a radical cam is from a mild one, and I believe over a certain lift you've got to upgrade your springs. I dont want that big of a cam, but what about roller, hydraulic and flat tappet? What are the difference, advantages and disadvantages to each? Someone please just give me a rundown on how I could build a little bit of power with this truck! Thanks fellas
