The C33DP is manufactured with a D-port flange for GM ZZ4, ZZ6, and LT-1 cylinder heads and fits various street rod applications. There is ample spark plug clearance, and the header is compatible with original equipment and stock-style steering gearboxes, Vega, and most rack-and-pinion setups (if the steering shaft hugs the frame rail).
