You might also ask if the headers will keep your flywheel from comming out without removing a header ran into this a couple of weeks ago. Also I would think about a heat wrap, wish mine had that!
i installed L&L 79750D long tube headers in my 68 F100 2wd...they are pricey @ $450. i bought them from jeff's bronco graveyard. 1 7/8" tubes w/ 3" collector i believe. i doubt they can be installed w/ the engine in the truck. but where there's a will and a big hammer, there is a way! i installed the engine with c6 attached and the radiator core support removed. when the engine was in far enough i attached one header bolt at the front of each side so i could still move the headers around as the engine was moved into final position. i actually performed this feat by myself...it was not easy, but the headers fit well on the driver side but touch the frame on the passenger side. a cutting torch can be used to make clearance.
if you want to save money and use manifolds, find a 460 from a 78/79 f250 2wd. i believe those manifolds fit in these trucks. cheers, garsten
I got a set of Tri-y Stans Headers (stansheaders.com) for my 68' F250. They fit beutiful and have a thick 3/8th flange. You might need to remove the two motor mount bolts, slide a jack under the pan and lift the motor a few inch's to slide them in. The headers also come with a gasketless slip ball collector far better then the 3 bolt collector flanges. Dont forget, you will need to either get a whole new exhaust, or make the exhaust you already have work. All headers have the collectors in different locations wether it be up/down, left/right, front/back. so to make them work with an old exhaust is sometimes not worth it compared to making a whole new exhaust. btw, The Tri-y's significantly changed the tuning of my motor. I atcually had to down in jet sizes, we all know, smaller jets means better fuel mileage.
