Well I have a picture of a cometic in the package. You can see the back side definetely has larger ports.

Can you take a close up of the rivets on both sides??? Note the position of the back ports as well.

Just mocked up mine on the motor and the driver side will have the rough side of the rivet up and the passenger side will have the smooth side up. That is the only way to get them on and line the back coolant passenges up. So Nate, yours are correct! And they would have leaked and the dyno if they ever were gonna leak!

no shi* thanks for the good tune!!!! are congradulations in order yet? Oh and the problem with the springs was the center spring was binding with the outer spring. I had to use pliers to pull the center spring out. NOT GOOD!!!! thanks for clearing this gasket question up john I was pretty sure I wouldnt cover up a port that big wierder stuff has happend though!!!!!!

Wow.... it is nice to get lucky once in a while. Mine are on correctly. Even though they didn't leak, it it good for piece of mind. You figure thet they could have had TOP and FRONT silkscreened on the gaskets somehow.. Especially for how much they cost...

with all the complaints cometics are getting you would think they would do something. even dabbing a bit of paint on the rivet tab, or maybe some instructions. oh well its good to have friends like john who is full of answers and is always doing something to his car big thanks john

Even if you flipped them and had the small hole on the big hole end, the hole itself wouldn't really make a diffrence in the cooling effect. There would still be a passage for the water to go through, it'll just be smaller. Granted they'd probablly leak because the big hole end dosen't line up that well with the small hole end. I still don't think the size of the hole itself has that much to do with it.

Here you go, I took a pic of the the rivets from the Cometic gaskets. Note the passenger side is right side up and the hole is smooth, the drivers side is installed upside down and the rivet is not as smooth and you can see a slit in it. Hope this helps...

No problem on the tune buddy! I take it the car pulls like a frieght train! I figured the springs should have enough pressure out the box, at least that explains it. We don't have a little one yet, but it is just any day now we should!

Default LS gasket installation

The transfer holes between the block and head are at the rear of all LS engines. You must install the gaskets correctly or the transfer holes will be blocked. On an MID block (pictured) you would also end up with a serious coolant leak at the front of the motor.

Coolant enters the front of the block via the pump. Most of the coolant flows to the rear of the block cooling the cylinders. Some is diverted through small holes in the head gasket to cool hot spots in the heads. The majority of the coolant however flows between block and head through the transfer holes at the rear. Coolant then travels forward through the heads picking up more heat then out to the radiator. If the gasket is on backwards you are in for some serious overheating problems due to vastly reduced coolant flow.

The first and last photos show correct installation. The center two show incorrect installation.
