I might've found a good deal on coated Pacesetter headers 1336. However they say the headers are for 5.0 (exclude tpi and 5.0HO) , but list no other alternatives for those exclusions. My question is would these be bad on a 350? They have the AIR tubes and everything, 3" collectors. Just curious. Anyone have these?

 

They say it will support up to 400 horsies.
So I guess thats good.
I own them on my TBi and I have had problems with leaks. Other than that they are decent.
For 350 you should be able to get some better headers though!

 

How long have you had them and where and when did they start to leak?

I know they are on the small side for a 350, but I just wanted some more horses, something smog legal, something new under the hood, the exhaust to sound a bit deeper, and to hook up to my stock exhaust.

 

THey leak on the right side head. I am actually getting the seal4good gaskets so I think the leak will go away!
When I put them in, I did not have all the tools I needed (braker bar) so I had to go to an exhaust shop so they can unbolt my Y-pipe from the manifold (It was stuck like a biatch). ANyways, when they connected my headers in, the ***** only bolted one half of the collectors and did not bother with the other. It has two bolt collectors, and they really don't leak much. Just make sure you re tighten those stupid bolts, or you will fight the leaks...
Trust me.

If you do everything right, these headers will defenetly help.
You can feel the difference once you put them in.
Laters.

 

Where did you get those gaskets? Checkers?
