You will enjoy the headers Harry
I have had them on my 440 for a year now.
they were a bit tight on the right side lower arm support bracket. I had to cut about an inch from the flange of the bracket. yours may fit just fine-- could be just a quirk on my coach. I didn't go for the coating but Thorley nickel plates them anyway for corrosion resistance. Use as many of the original exhaust studs that are in the head as they are a better way to keep the headers tight and the bolts go directly in to the water jackets of the heads. I don't recall if I had to use any header bolts but if you do be sure and use a hi temp sealer on the threads to avoid any leaks. recheck the bolts a few times after you have ran the engine, I also used hi heat sealer on both sides of the gaskets before installing them. let us know how they fit for you.
