Won Hedman hedders on eBay the other day. These are Hedman 88300 and are supposed to be new. I decided to go for these because I probably will have to modify them to fit the 351W. If they are far off I'll just sell them to some Mustang guy. The headers should be here next week BTW anybody tried these headers with a 351W?
those are 302 headers. they probably will not fit a 351w. i believe the 351w headers go closer to the engine as the engine is wider. therefore the 302 headers stick out more and will not fit. someone else will correct me if i'm wrong,
Hedman also lists these headers for cars with 351W like Torino and Ranchero. I have 302 heads on my 351W so the angle of the flanges should be the same (maybe it is the same anyway). 302 people have been having clearance problems with the steering valve with these headers. Since the 351W is higher this problem may be less with the 351. I will at least try them
