I'm going to be installing a skunk2 header. Do I need a brand new engine to header gasket, or do some people just reuse the old one?

 

Oem one is very durable and can be reused.

 

You don't "need" one, but if yours is very old then it is $9 or so at most online Honda parts shops. If you are doing that, then I would also recommend a new set of 7 exhaust manifold nuts for another $16.

 

Do the nuts stretch out or something?

 

The head gasket is ~$60 and I would run away from any head gasket for this car that's $9(you get what you pay for). The head bolts stretch when you tighten them, but that doesn't mean you can't re-use them. You have to measure the width of the threads at the tip.

 

Slowcrash, think he meant exhaust header gasket. Not head gasket.

 

Yeah, that's right exhaust manifold gasket. Sorry, I typed this very early in the morning. Lol

 

Yeah something like that. They lose some of their lock nut properties the more you install and remove them.

 

Easy there champ. Read my friend, read.
