header question

[Irish_Alley]

Lmao I was hoping that's what you ment:

My real world info then is wrap your headers  Youll extend the life of those headers and squeeze a tad more performance out of them. 

[beastie_3]

Wrapping headers will void their warranty, and if they are cheap headers, they will warp and rust.

yea thats what it thought, ^^^ i know its better for them but ive heard of people cracking them because of hot spots where its not fully wrapped, and there cheap ones they will most likely warp at the flanges anyway.

Pete,
I'm looking to do the same thing before spring. If you would, let me know what ended up working out the best for you. I have an 80 Chevy swb c-10 with a 305. Thanks!

hey guys put them on and they were ok fitting, my opinion is to get some quality stuff to not worry about fitment.

[Jim Rockford]

This is what happens when you wrap headers.

Wrap keeps moisture on the headers ans DESTROYS them, as the pictures show....

wrapping headers is bad, but is the sleeves on the plug wires okay?

[Grim 82]

Yes, and depending on which headers and plug wires you have, they can be absolutely necessary to keep the wires from melting. Look at the picture I posted on the first page. My plug wires are nearly 3/4" in diameter with the extra shielding, which is double any stock wire I have ever seen.

i dont think they are needed, just another way for someone to make money

It's a way for me to make money. Those wires were $150, and the sleeves are cheap insurance so I don't need to buy another set

[1979C20]

Grim, I've got the 8mm double insulated wires, and the number 2 plug wire touches the headers in like 4 spots. The boot for the plug, and the wire itself. So, my truck starts running like CRAP because it begins arching off onto the header and I get a miss fire. I have to stop, pop the hood, and move the wire off the header. So, I'll look into those sleeves.

I run the "socks" and have no issues since I got them.  Prior to that, my wires melted too many times in 2 months...
