For this build I used a set of Kooks 1-7/8” stainless headers. These headers are designed to fit on an LS engine in a Gen 1 Camaro with a stock front sub-frame. Expensive but very high quality... and a perfect fit right out of the box. These headers came with some adjustable engine mounts (Dirty Dingo) but they were bulky and didn’t clear my dry sump oil pump… so I bought some Hooker engine mounts (p/n HOK-12624HKR) 0.5” offset. These mounts fit well and put the engine in the correct position.
The Kooks headers cleared the AGR steering box; pitman arm; and the Z-bar linkage for my mechanically operated clutch. These headers fit better than any I’ve ever used.... good ground clearance to. These headers were built with the LS7 flange to match my heads.

This shows the fit on drivers side and clearance on the steering box.
