I'm in the process of putting together a stock 4.8 w/ LS1 gaskets and Alper head studs. Stock 862s. Real budget motor. Looking to eventually push 15lbs with my Huron Speed truck kit and a TC78 or if I come up on a good deal a PT7675. All this in my 99 SS 6spd car. Also will be running a Vic Jr eventually.

So here's my question, a friend suggested using Copper head gasket spray and said it will help from pushing water/added insurance. I searched it but couldn't find to much on it then again who can ever find **** on this site anymore. Pro's vs Con's? Do's/Don'ts?

My buddy builds Grand nationals for a living making crazy hp on tons of boost and he swears by copper spray he uses it on every build from restoring one to just stock to 8 & 7 sec 1/4 mile cars he sprays everything head gaskets turbo flange gaskets exhaust flange gaskets so it's good stuff so I definitely recommend using it

some people use it, some dont. I did spray my ls9 gaskets though.

Take the gasket rivets out and coat the layers one by one then stack them back up in order and install. I always use permatex copper coat been using it for years never had an issue doing it this way.

For the guys who are spraying their gaskets,are all of you using the drill the rivets and spray each layer method or are some of you just spraying the top and bottom?

i sprayed top and bottom then threw them in with out spraying all layers just to make sure there was good adheasion to the deck and heads since that was my only concern

Are you guys just using the permatex brand like at advanced. Auto?

^I believe so. Thats what i was told to use. Nervous about drilling the rivets to spray everything.

I guess it won't hurt, especially since the heads and block arent decked It will only help.

i was thinking of the same thing, but I dont think I need it since i have fresh surfaces on the heads and deck... But I still might

The riveted part of the gasket hangs outside the head/block when installed its only purpose in life is to hold the gasket together until it is installed. Nothing to be nervous about at all just stack it back in the order you took it apart in.

We spray top/bottom then install. hit 24lbs of boost on my 427ci no problem.

I wonder with the people that take them apart if they also drill the coolant passage holes to line up since some aftermarket heads are off.

It costs 7 dollars for a can of that stuff just use it its not going to hurt.

F it I just bought some for the hell of it... You have a point it won't hurt anything ^

I'm not going to spray every layer and pop the rivet out though, the gaskets are too pretty to do that...

^Tis my plan at the moment. Like you said it can't hurt and will only help seal block and heads!

Many people only spray tops and bottoms... i did the same and work well.
I have been doing this for over 15yrs on every engine i work on.
