Headers w/ np435
I have a 67' f350 with a 352/np435 and I'm looking to run some full length headers. I'm planning on investing some $$$ into ceramic coated hookers. I'd like to here from guys who have put headers on an FE themselves.
Would also like to know whether they go over/under the crossmember, thanks.

For clarification, 2wd or 4wd?
Either way, they should go over the crossmember... tougher to do on a manual trans rig than an automatic but not impossible... gotta find a good muffler shop (2.25-inch or 2.5-inch tubing) to snake it by the clutch linkage. However, most will opt to have both tubes go down the inside of the passenger frame rail. Alternatively, get a U-fit exhaust tubing kit from Speedway Motors ($140!) and show us your skills!
I saved a pic of someone in there who clearanced their crossmember with half-moons made from like 5-inch diameter pipe so the tubing ran "through" the crossmember.

Is your engine and crossmember the 3 point with front mount comming off of the timing chain cover and the two rear mounts off of the bell housing or the standard 2 mounts either side of the block and trans the rear mount. Im just wondering if the 67 350 is the same as the 4wds from 61-66 if so the headers will go under the rear crossmember. I believe my muffler shop ran
3 1/2 from the header to the flowmaster single muffler with a 2 1/2 exit where the stock pipe would have. It was run down the passanger side as was stated before. I did not dual it as I wanted to leave a little back pressure for more low end torque and I dont race the truck. If its not the front motor mount to timing chain never mind.
Edit: Flowtech long tube headers is what I went with.
outside the truck drivers side
passanger side

Hope this is helpful for you

The header collectors will point under the crossmember but they should not go under the crossmember.
Below is a comparison of my 4x4's (2wds will be identical) old dual system and the collector tubes I fabricated to orient the system down the passenger-side frame rail.
Here they are installed... over the crossmember.

I ran mine down both sides..........
This was done 10 years ago, and I will be replacing them with Hookers Headers myself. I am going to wrap my headers this time with some thermal tape, so have decided against the coating.

Im out in left field then. I thought that 76 F350 would still be the 3 point mount with the front mount comming off of the front of the motor and the 2 rear mounts off of the bellhousing. If this is not your setup forget all I have said and I will slink away quietly letting the thread roll on.
