Major exhaust man problem!!

[TYTILIDIE]

Damn, after all the crap I have gone through with this build it just keeps getting better. First, I had my manifolds baked and they turned out absolutely beautiful. Well, my goal was to have the motor in the truck tomorrow and start on wiring. All I had left to do to the motor out of the truck was install the exhaust manifolds. Everything else is done. So I go to put them on and realize the holes don't match up. After chatting about it with the machine shop, I came to learn this far from uncommon. They sold me a spreader tool which worked great. Problem here is, the manifolds don't clear the ARP nut and stud for the heads. The $1800 headers you see everywhere is no where near a reality or an option. Gorgeous but no way would I pay that for headers. I am not sure if I should get some copper gaskets and shave some of the manifold off or build me some headers. I have the skills and tools to build the headers, with some major help from CRITICAL of course (don't want to leave out his props or I could get yelled at:lol. So what would you guys do?

Re: Major exhaust man problem!!

try a heat gun , I heated my manifolds up and they slid right on . how far off are your holes vs. studs ??

I would just use regular bolts instead of studs, I can't imagine you would ever be able to remove the manifolds with the engine installed. If I was going to bake a set of stock manifolds, I would bolt them to a set of spare heads.

i would use the pro series bolts where it hits the manifolds..

Throw them in the oven for 20 min at 500 degrees. That is what T-jay and I did when we put his replacement one on! Worked great!

but wouldn't that crack the powder coating when you stretch it?

Got them done!!! We ended up using the separator tool on the big part then heating the piss out of smaller run. He had a torch on it for a good 20 minutes and tapped an impact socket in there to spread it out. I was very surprised how fast and easy the socket spread it apart. I think I am still going to explore building a set of headers though. Something tells me these bolts wil have to be cut off when I want to take the manifolds back off.
