Default Cap of polution control holes???

The holes on the back of the factory heads...I really don't want to just crimp the pipe off that comes from the back of the heads, so I was wondering if anyone is making something to plug with or justa simple fix of some kind??? By the way they are GT40's from a Lightning truck...

The plugs you are looking for are called thermoactor plugs.
You can also use a 5/8'-11x3/4" longbolt to thread into the holes when you remove the air tube. You may have to clean out the carbon from the threads to get the bolts in.
