Why you dont use pacesetters with 3500 heads

To make these work I literally beat it in with a hammer. it also hits the tranny where the flange in welded. I stacked header wrap and wrapped the transmission connector, still melted it a bit.
Now you know

That's why you don't use Pacesetter headers period.

They may not be the best. But I havent had issues with mine. And they are the only ones out there other then MMS headers that clear the 6 speed shift linkage.

I had already taken my stock exhaust off when i was putting these on a while ago. did what I had to to make them fit. I think the fitting issue is with just the 3500 heads...
They are either going to be garage decorations, be sold, or trashed.
I just wanted people to know what $400 will get you.

Well with the big dent in one of the tubes. I doubt anyone would buy them.

And yeah it could just be with 3500 heads but who knows. I dont have 3500 heads so I cant verify that. But clearly you had an issue. I plan on upgrading to mms headers one day. But for now my pacesetter ones will have to do. I just think its kinda cool that only pacesetter clear the 6 speed linkage... s&s, Tog, and any others have been verified that they dont clear. Other then MMS ones of course...

^ this guy gets it! if you're still planning on a 14:1 compression ratio, i agree with Starglow

seriously tho, i had no idea 3500 heads were that different. with all the work you're doing, you don't have a welder? could of made a primary that fits. (buy a $2000 welder to fix a $400 set of pacesetters )

good luck and keep the updates coming

That pretty much sums up what every car guy is about...

He'll have fun building something, then blow it up, then have fun building it back some other way. In the end, he'll either go broke or will prove out a combo that works...which is pretty much what we all do once we graduate from bolt-on junk.

I don't think the issue is the 3500 heads. The exhaust ports are in the same place as the 3400 heads. Plenty of people have done 3400/3500 hybrids using both stock exhaust mani's and aftermarket headers. I think the problem is in pacesetters crappy build and quality control.

PS. I'd be kind of worried about what the heat from that primary being so close is doing to the plug on that transmission wire harness.

I'm sure the fact that pacesetters clear is pure coincidence due to their terrible design. None of the other headers clear because they weren't meant for cars with manual swaps. They were designed to be the optimal design to work in cars with the factory engine and transmission. Milzy's clear because they were designed from the start to clear multiple transmissions, which is part of why they are the best and most expensive ones available.

Strange....I had a related issue when installing 3500 heads on my 3400 block. Actually, the issue was with the LIM. When we went to bolt down the LIM, the diagonal bolt holes in the LIM were slightly off from the threaded holes in the heads - had to mill the LIM to get a good fit.

Milzys headers are obvious. He wanted a one size fits all. I keep up to date with Milzy very often. I know things that might/will soon be available for the n bodies before most people do.

Say what you will about pacesetters. Like I said, sure they arent the best but at the time I got them. It was the only option, and I have not had issues.

Now you know
think that you got a set of the first ones before they fixed this problem. I have a full 3500 with pacesetters and no clearance issues





I will try to get some better close up pics on the weekend. I have no problems with mine, would take them over TOGs/obx any day. s&s would be 2nd choice. If I was going for an all out build I would go custom.

um... no. TOG's were the best quality ones behind Milzy's. I should know, I've installed several sets of both TOG's and S&S on several peoples cars. The TOG's cross over pipe was a pain to line up, but other than that it was a better design than the S&S. The primaries were larger, and they had the O2 sensor properly located which the S&S did not. OBX are junk just like pacesetter. Really, modifying a set of TOG's with v-band flanges like I did to make mine easier to remove/install is the ideal setup, other than getting a set of Milzy's headers at least.

But if you have the money to fork over. Get mms headers.

What?! that pic pisses me off! haha jeez where is the quality control pacesetter? Even comparing the pics of mine and yours they look different. I had to remove the fan shroud diverted thing cause they didn't clear.

I dont think Im going to re-use these ones...

Ive put plenty of thought into MMS headers, thats a good handout of cash though.
Ill scout the for sale forum for some TOG's. I dont really like the s&s design like Aaron was saying, the O2 sensor only reads the front bank.

If anything try and buy another set of pacesetter if your desprate. If they dont fit. Return them.

Also another option... have a shop make a set.

hmm I could have the front bank modified. one thing I didnt like about them is where they connect(the ball side?) the opening was only like 1 7/8" I cut it back and opened it up to like 2 1/4"
