i'm ordering a header from racing beat and it doesn't come with the gaskets. So do i need the engine to headers gasket or the engine to headers flange? or both? and do i need to replace the o2 sensor?

 

The engine to header gasket is the OEM metal gasket. Most of the time this can just be reused. Getting a 2.5" gasket from RB for the other end would be a good idea.

Also, what are you bolting this up to? RB headers and downpipes are all intended to be used with their presilencer, which is longer than the stock main cat. If you try to bolt one up to a main cat, you'll end up with a ~3" gap.

 

thanks

 

and yeah im just running open headers for now but running the full exhaust later.. just needed the headers attached to run the coper wire for the mechanical choke on the holley
