I want to put a 351W in a 67 f-100, and would like headers. Since there are not any in the books will 302 headers fit the 351W?

 

The Equal Lenght Mac Headers I Had On My 91 302 Fit The 351w I Now Have In My Truck, But I'm Not Sure That They Willfit Your Truck, I Had A 1975 Supercab With A 360 Went To A 351w, Found No Headers For That Swap, I Think If Your Truck Came With A 351 As Original Or Has A Option Then You Can Find A Set Somewhere To Fit, But Check Online, Perhaps Someone Makes Some For Different Swaps.
