i am trying to decide which mod to do... i dont want to spend 800-900 on headers so that rules out the ASMs or the TOGs.... what are the best headers besides those?... are hookers any good?.... would i get a better power gain out of electric fans?

 

Go with the Thorley headers 15-20 HP.

5-10 HP with fans.

 

for headers, i think if stay away from shorties you should be alright. try to find a good price mid or LT.

e-fans from a TA or camaro should be the cheapest route.

 

heck yay throleys. good price. then get some ls1 fans for 75 to 100. and then a harness for around 80. then you will be set.

 

Check ebay. I paid $150 for a set of Thorley's

 

If you get the fan's you will save money and gas. So it will pay for both in the long run.

 

plus, you can pick up a set of fans for relatively cheap. I think a local shop had some out of a firebird that was t-boned for like 150 bucks..i'm sure you could find some deals like this

Thorley headers! LS1 fans are relatively inexpensive. Sometimes can be had on eBay for 100 bucks.

 

does thorley make headers for 2004 4.8L??? if so where can i get them?

 

Not sure if there are headers for your application but you can check them out at Thorley . If you don't see anything online give them a call or email under Contact Us on the home page.
