I am swapping my headers and I pulled the driver's side tonight. I was gonna pick up some GM gaskets, but my friend got his Kooks headers for his GTO and they came with these black gaskets that are for lack of a better term, fuzzy. I think they are Percy's of some sort, and I think he said he'd just give them to me (he bought some GM pieces). Anyone using these? GM ones recommended over these? Thanks.

sounds better then pacesetters copper ones that i just put on haha. if your tight on money id use them other wise why not spend a little extra for a little more peace of mind.

 

why not use the factory gaskets? I have changed headers twice on my car and have just reused the factory metal gaskets. No leaks or issues, they seal up great.

 

im just going to get some factory gaskets when my pacesetters come in friday every says there the best

 

Yea I'll probably go grab some from the local dealer. I hear good things about the XXX carbons but it seems it's the same 2-3 ppl, nobody else uses them

I use them...they are PERCY CARBON XXX ...they are good....17 months and not a leak at all....I am happy with them.......I was directed to them by a local engine builder...all he uses is them and the SEAL-FOR-GOOD [something like that ]...

 

reuse the stockers, mine sealed great on reuse. Just make sure they are in good condition. If not, just buy new ones. GM made good gaskets for our headers.

 

The stock ones work great and so do these:

My friend uses those Percy's carbon fuzzy gaskets and his headers have been leak free for about 2 plus years now.

 

I put those "fuzzy" ones you speak of when I did my header install. They came with my headers, and there are no leaks.

 

Anyone used the aluminum Flowtech's? All the local auto parts store had was Mr. Gasket paper's and the Flowtechs. I got the paper ones because the flowtechs were like 20 bucks and I didn't want to waste my money.

 

get the fel pros

that never leaked on mine....
mac's
pacesetter's
and now slp's

 

Stock gaskets are just fine. I've had headers on and off of my car 6 times still using the original stock gaskets and still no leaks.

 

My collector bolts (all 3 of them) rattled out somewhere between leaving for the track and leaving the track last thursday. So yeah, the stock gasket went bye bye. I threw a paper Mr. Gasket one on there for now and it isn't leaking so far. Of course, it hasn't gotten wet either.

 

I'm the friend and like he said, I've been using them for over 2 years now and have had no problems.

 

I have never had a problem with paper header gaskets, they work fine as long as you keep your bolts tight...and don't have warped flanges. Yes there are better options out there, but if you have paper gaskets I wouldn't worry about it.
