Hi guys, I'm having a very hard time finding headers that will fit past the friggin slave cylinder on my 86 2WD! Every longtube design is built for auto trannys. Any ideas? That aren't mega expensive?
Why not get some shorty style headers? I got a set of mustang cobra headers for the 302 in my Capri for $5. Check your local craigslist or other classifieds.

thanks guys. I've checked with Hedman, Hooker, and flowtech. They're all built for automatics. There are some mid length headers from hooker but they're about $300 from what I've seen. Way too much. I wish my long tube BBK's would fit. They were on this engine in the mustang!
It will sure be better than the cast iron logs you have now. IIRC the long tubes help improve low end torque while the shorties help top end HP. I think...cant remember right now. Someone will correct me if I'm wrong though.

Yeah, someone was saying they saw a dyno where long tubes did better down low and up high, but shorties gave more in the middle. I don't know for sure, but I do remember that was exactly what was said. Someone on these forums, but I don't remember where or who.
Shorties are $300+ on summitracing, while long tubes can be gotten for around $140. Why? And where else can I get some good shorties for $150 or around that area.

OK... I see your problem, you're trying to use mustang headers on a truck, that's guaranteed to produce interference problems, avoid at ALL costs. I bet some truck specific headers would work. Here's a pic of the Flowtech longtubes on my truck, I don't know where the clutch linkage is on a manual but you can see the collector is towards the bottom of the tranny for the most part.

Who is looking at the wrong thing? Me or him? When I went to summitracing, I specified long tube headers for an 86 f-150 with a 5.0EFI 4x4. It shows up long tubes and short tubes, but it doesn't say anything about auto vs manual. I just assumed that long tubes wouldn't work in general with a manual because of the OP.
So, I CAN probably get long tubes?

I'll bet you would run into heat problems and clearance with the external slave cylinder and mounting bracket on the manual trans judging by those pics.........
It really depends on how far the spread is on the headers as to it clearing the slave. That's why I suggested going to an internal slave cylinder. In any case, you are STILL going to have issues with heat and the plastic hydraulic tubing to the slave.
If the longtubes would fit, I could just use DEI heat shields to cover the slave and lines. I thought about trying to use a later model shaft mounted slave/bearing but not sure if it's possible or worth the trouble. Those pics seem to show that the header will run underneath, but close to the slave....... hmmmmm
By the way, Conanski, are those Flowtechs the 12502flt number?
Yeah, someone was saying they saw a dyno where long tubes did better down low and up high, but shorties gave more in the middle. I don't know for sure, but I do remember that was exactly what was said. Someone on these forums, but I don't remember where or who.

Not exactly- I said the long tubes only made about 5-9 points diff in the torque and horsepower and the shorties actually made more torque. You can see the dyno test if you Google up long tubes vs. short tube headers. To refresh your memory, the thread was "cheap easy mods" in the small block engine forum where the OP was trying to put headers in a van and had some factory shorties that Conanski really liked a lot and is hoping to get for Christmas.
Someone will correct me if I'm wrong though.
