So I have BBK hearders on my car and the one on the driver side seems to be leaking. How hard is it to change the gasket or what do I need to do?

 

well its guna be like when u put the headers in and the motor may have to be jacked up a few inches, and when u replace the gasket u have to tighten the bolts starting at the middle and working ur way out to the edges torqueing bolt a little bit at a time.
