I need to chase the threads in my cylinder head for an exhaust stud. Can I do this with a thread forming tap or is a thread chasing tap a completely different animal? Please explain if I shouldn't use a thread forming tap..



I'm having trouble finding thread chasers that are long enough to chase the entire depth.

I can purchase a thread forming taps easily..

Thank you,
