Holley White box long tube headers (open header cold start)1986 f150 351w np435

these Holley headers are a huge upgrade over the old pace setter shorty headers. They cleared the hydraulic slave cylinder with ease and fit great. will need to pull the passenger side back out and clearance for the top and bottom of the frame.

You have the part number on those? I have a 95 F250HD those should fit nicely.
By the way, nice truck.

Thanks! The part number is White Box WB10020. They do fit great. I was concerned about the clutch hydraulic slave and line, but the driver side fit like a glove. The passenger side contacted the frame and needed to be clearanced.

Could I send u pictures of my motor in my truck I’m trying to figure out if I have a 351w

[@brokewheels5]

I probably wouldn't be able to tell without seeing 2 engines side by side.
