I have been looking around for a long time now and trying to find headers that will make it past the 88 5 speed belhousing is a pain, I have the 1978 cobra 11 running a 302 with 289 heads, the trans came complete from a 1988 and when I tried to reinstall the m11 headers well they hit the bell on both sides, years ago I seen a set of shorty replacement headers and didn't get them as I was still running the original automatic, now I am using the stock manifolds but really want the motor to breath better with headers, anyone have any good idea's??
