LS Motor mounts w/79 camaro clip

[MyDream55]

Hello all,

I have a 57 pickup with a 79 Camaro clip and an LS1. I am looking for some motor mounts that will raise the motor up a bit (or another suggestion as I have already moved it back as far as I can go). The current mounts I have will not fit any headers I have tried. I'm sure there is somebody on here who has done this and can point me in the right direction. I am getting frustrated as I have tried 3 different headers and they all hit on the frame or control arms. Thank you very much.
