Help! Am bulding a 421 sbc for my 79 Monza. I realize header selection is somewhat limited. Can anyone tell me if the 2129's are still the only headers I can use? I have tied the frames all the together, using hooker front mounts, and converted to rack and pinion steering. Does this open a window of opportunity to use a wider range of headers ie... camaro,Nova,G-body etc? Any feed back would be greatly appreciated. Thanks.
