Just curious if I should spray anything on my cometic head gaskets. I've seen people using copper spray or hylomar(sp). Just wanted to see what the popular opinion is now.

 

Cometic says install them dry, do that's what I would do.

 

I sprayed mine w/ copper just to be on the safe side. So far no problems.

 

I've installed both sets of mine with a light coat of copper spray gasket. Haven't had any leaks thus far. Only heard of leaks with people who've installed them dry. It's up to you though.

 

I install all the mls gaskets with a light coat of copper spray, and never have any problems.

 

Different platform here, but I run cometics, and have only had problems when installing them dry.

No problems whenever I've used copper spray, which has been 3 times now.

 

copper spray will not hurt anything. i always use it no mater which gaskets.

 

Used SDE Titans with std ARP studs...they recommend installing dry. DO NOT! Started seeping before start up!!! Quite a few people are now using Yami Bond #4 or other good sealant before installing these or other aftermarket gaskets. Removing and going w/ L-19 studs and GM MLS w/ copper spray...this better work!!!

 

same here. always install them with copper spray and no leaks.

 

I used copper spray on my .40 cometics and I have had no leaks. My brother did the same thing on his 04 Ls1 gto with the .40 cometics and he has had no leaks, so I would definaly spray some copper spray on them rather than take a chance and maybe have to pull the heads again or even worse ruin your bearings with coolant.

 

i had a set of the sde gaskets seep also. i did them dry, then i went to a secret wepon, and it held up perfect to 350 worth

 

whats the secret weapon??? lol.. ive heard people running some special type of sealent ( something else besides copper spray) any idea of what it might of been?

 

if i tell you, it wont be a secret.

i know what you mean tho, its that yammabond stuff, but it makes a mess, and my secret wepon is working, so its for sure you can make 800-1000 rwhp on spray without lifting the heads!!

i charge $50 a head for anyone who wants to know the secret. make checks payable to NOYZEE racing. lol

 

NO FAIR

im near that power range...... please.. lol

 

Check is in the mail!!!

 

tell me your power, send 50 bucks, and its yours. lol think i will have to become a sponsor for this

 

if i knew it was that easy i would have started higher.




Please note: Do to increase of living and expenses, there will be a price increes on the secret of keeping the heads down on your lsx. new price is $200 per person, and a sworn secresy document must be signed or you will go to hell.
