I originally bought these THRUSH headers off ebay with the thought of mounting them on the stock 289. Didn't anticipate any fitting problems with the new 302. The left driver's side header gives me zero clearance for spark plug boots 5,6,7 cylinders.
The right passenger side header Flange is very uneven at the number 2 exhaust port. The welds are excessively big. We checked the flange with a straight edge and it's pretty flat. Just the puffed welds are too large....(explained right?? )
Also, that same tube is hitting my ARP stud on the cylinder head.
My neighbor, my dad and I were thinking to take the headers to a machine shop and get the flange "planed" flat. Then take them to a muffler shop to get the tubes bent so I have spark plug and cylinder stud clearance.
What do you guys recommend? I know you racers have encountered these problems one time or another.
Sorry for the lengthy posts. I just really want to get as much info as you guys need so it's easy to understand.
Thanks SOOOOO much in advance!!
p.s. I'm using Ford Racing spark plug wires and the boots are about 70-80 degrees angled.
