hurry up and let us know how they turned out already! im getting anxious

 

you can use factory gaskets ? you don't need header gaskets ?

 

Factory gaskets ARE header gaskets. The stock exhaust manifold is a header, just a real crappy one.

 

The 5.7L manifolds look like logs to me. The 6.1L manifolds look more like headers.

 

Remflex gaskets are supposed to be the best. I just bought a pair to use on my truck. CarQuest carriers them.

 

what kind of headers did you get? Long, short or mid?

 

I have jba shorts. so for my 4.7 I can use stock gaskets ?????

 

No doubt they look like logs, because they are logs. Log style headers :-)

 

i got 400 miles on the headers now and no leaks re-using the factory gaskets that were already crushed...lol No silicone was used either. i hate messes.
My butt dyno isn't spectacular so IDK if they made any difference. It's hard to tell with a sloppy tranny.
