Dynatech has taken out all of the guess work when it comes to selecting the right header for your race car. They thought of everything when designing these headers:
CNC Laser machined flanges feature raised port location for increased power
360° port gussets that eliminate cracking around the flange seams caused by muffler applications and tire shake
Large radius, CNC mandrel bent, equal length primary tubes (32'' SBC-Up swept, 30'' SBC-Down swept and all BBC) that are available in straight or stepped diameter tubes
Jig-located U-tabs for easy, hassle-free bolt-on collector installation
High temperature, silver ceramic coated inside and out.
