Yep! I had to replace the driver's side exhaust manifold gasket. There was an exhaust leak. Yeah its an FE 360! Well 3 hrs. of working the bolts out with heat and PB Blaster I still broke one off in the head, but did not skin my knuckles. I got to say it was a good day.
and unless you wrap the starter with a heat shield..you will burn up starters
my headers or starter are not wrapped and the starter is fine,its never failed do to over heating. if you have a heat problem then run a heat sheild.i would try it and see if you really need to sheild the starter first.both my 302 and my 428scj run big tube headers no sheilds,no heat problems. it works for me anyway.
on a 335 series motor you'd be looking at a 40hp or so gain over stock. the one i have sit awefully close to the trans i am gonna go with the fender exits this year
I Just put a set of Dynomax headers on my 79 F150 2WD 351M, love the sound. The guy I bought them from told me the more money you spend the better the headers in overall especialy the fit. I ended up replacing the starter to a mini for clearence issues and wraping it.
I haven't installed headers on my trucks, but if I did get the cheaper ones, I would use a straight edge on the flanges to check for true, and grind or mill them flat where needed.
An old trick for FE bolt removal is to run the engine until hot, then start cracking the bolts loose immediately after. (wear gloves! LOL)
My 460 is hard on the starter when hot, so I will likely install a heat shield, but I would also like to eventually go with a gear reduction starter too.
I pick headers over stock manifolds anyday... The newer cars with mod motors don't seem to respond with as much hp gains with headers, so stock manifolds in those cases is going to save the headaches of installation.

*sigh*My son had PaceSetters put on his 06 F150 5.4 The shop didn't replace the heat shield (they also bolted them wrong but that's another story) because you can't even fit a sheet of paper in there. Unfortunately, they also didn't bother to tell him it could be a problem. Fast forward 10k miles & the starter overheats. Truck starts fine cold but once the starter's hot & turned off, has to cool for about an hour to start again. My son's in the Army & just left for Germany so Mom gets to take care of the truck. lol Removing the headers isn't an option because my son likes them (besides, he didn't get the stock manifold back from the shop). There's not enough room to wrap the starter as is so we were looking into replacing it with a smaller, performance starter, then wrapping it. That's where we ran into a problem. We tried a couple of performance shops & they had no idea what to recommend. It would be great if the stock starter could be wrapped but besides not having enough room, since it's been overheating, I imagine replacing it is the best option. Suggestions?
Thanks!
when you install the new starter wrap it before hand with the header wrap or vice versa wrap the header before you install the starter. even a piece of 14g sheetmetal wrapped around the starter would help alot
