Im about to install some Kooks Long Tubes on my ls6. Two questions:

1. Many people say to ditch even the newly designed aluminum gaskets supplied by kooks, and to just use the OEM GM Gaskets. What do you guys think?

2. What kind of spark plugs should I throw in? Bosch Platinums +4?

Thanks!

whatever you do... do not use paper gaskets! i just had to replace some paper gaskets that shattered everywhere. i picked up the some felpro metal gaskets at o'reilly for like $15 and they are holding up great.

I put the gaskets provided by KOOKS and so far have no leaks. they have been on since October with no issues

Your inout is much appreciated. HOWEVER, Kooks recently stopped using the carbon xxx gaskets, and now supply the header kit with aluminum ones, I WOULD LIKE INPUT ON USING THESE ALUMINUM ONES.

The GM originals are without a doubt the best. I'm still using my stockers at 10 years old and 120k miles with no leaks.

so noone can comment on these aluminum ones? I guess thats a bad sign. Where can I find the best price for OEM GM gaskets? ls6.....THANKS

Just reuse the OEM ones on the engine right now. They are next to impossible to destroy and seem to last forever.
