Top 10 Most Frequently Asked Questions:

1. When using copper head gaskets do I have to o-ring my motor?
No, you can use our ICS Titan head gasket which has a built in combustion seal. The ICS Titan head gasket is strong enough for almost any combination which can be driven on the street. However, for the most extreme pro-level racing only combinations O-ring combustion seals are best because they “anchor” the head gasket to the block or head.

2. I want to run my car on the street but copper gaskets are known to leak coolant, is there a way to prevent leaks?
Yes, if your engine has O-rings in the block or heads use our Titan self sealing copper head gaskets, you get the unbeatable strength of copper gaskets without the worry of coolant leaks.

3. Can I install an O-Ring the head or must it be in the block?
The O-Ring seals equally well in either the block or head, however it is usually easier to install in the block using a boring bar or a manual O-Ring cutter.

4. Are there any recommendations on how to O-Ring an engine?
Detailed instructions are available on the Engine Preparation page.

5. Are copper head gaskets reusable?
Yes, they can be reused several times as long as there are no signs of failure, such as carbon tracking beyond the O-Ring.

6. When installing embossed copper exhaust gaskets, which side goes toward the head?
The flat side of the embossed copper exhaust gasket faces the head. The embossing allows for any irregularities in the manifold or header.

7. Are copper exhaust products reusable?
Yes, Copper exhaust gaskets can be reused several times as long as they are re-installed on the same flange from which they came.

8. Do you make a 2 ½ exhaust gasket for the BBC?
The 2 ½ is the outside diameter of the tubing, the 2.385 port size on our gaskets are made for this size header.

9. Does SCE make custom gaskets?
Yes we do, however with the large number of gaskets we currently produce, there is a very good chance we already have one to fit the engine in question. Check our online catalog first to see if your gasket is available.

10. Do you recommend a re-torque on head gaskets?
Yes, since our gaskets live in the extreme conditions found in High Performance engines, SCE recommends a re-torque on all head gaskets.

11. Does SCE have a high performance head gasket other than copper?
Yes, our Pro-Seal performance head gasket is designed specifically for street/strip or naturally aspirated racing engines.
