These performance headers will also work with 610 and 710 and they work with L16, L18, and L20 conversions. These headers are new in the box.
This header system has adjustable length header pipe for ground clearance on lowered cars. These are square port headers but will fit the round port and work PERFECTLY. The primary pipe diameter is 1 1/2".

We are the only company known in the Datsun performance sector that manufactures these custom headers.
