Hi Dan, Thanks for the e-mail. The only kit I could give you would be 3/8" flanges, slip on collectors and U bends which would be about $432.
Although the header we make for that car is based on the engine in the stock location and we can compinsate for the tall deck and any head type. We can make any tube size you need up to 2 1/2" and any collector size up to 5". Our design has 2 tubes on the passenger side going around the frame and 1 on the drivers side around the frame in order to get more oil pan room. The collector end up along side the transmission and it's a merge type collector with a trasition cone inside. We have 4" of clearance from a stock oil pan on both sides. Will that clear your starter on the drivers side and your dry sump lines? This header will also clear mid plate or solid side mounts. We charge $850 for them stepped or not. Thanks again, Dan Lemons.
