month later, but finally got those damn headers in. and no it wasn't a month of trying, just busy doing other things. Ended up hoisting the motor/trans back up a bit, drivers side went in fairly easy with the oil filter off. Pass side, I took the drivers side back off, hoisted it up some more and fed it up from the bottom, forcing the motor over to the drivers side to give me the clearance i needed. You have to get them into the bay and held off to the side while you lower the motor back down slowly, making sure nothing binds and they're still where they need to be. Passenger side header hits my control arm bracket, but that might just be my tweaked out frame and poorly installed motor mounts (from the previous owner) causing that issue. Looks like it bolted flush and will probably clearance itself over time (or so I keep telling myself). Both go in from the bottom from my experience with the car up on ramps and the motor/trans raised up and tilted cause I had a load leveler on it. Not fun, not easy, but they do fit. Starter and oil filter were not in for the install. Starter did fit back in with the passenger side header bolted down, so shouldn't need a mini starter, but damn is it close to the header. A heat blanket might be needed further down the road, not sure yet.
You definitely want to watch your wire placement though. I ended up getting a longer positive cable for mine so it's not flat against the header. Some careful placement of zip ties or electrical tape can keep the other wires going to your starter safe. Granted, most of the wiring in my engine bay has been customized by "that guy" so your experience will be different from mine. I do plan on going over the engine bay later and deleting alot of unnecessary wires with dead plugs. Figure out what I need and run it from the correct place with fresh wire tucked against the firewall and away from heat points. Right now, I'm just happy it's running, burning the new paint off that I put on (yup use header paint instead of engine paint) and will most likely go with shorty or clipster headers next time around. This is a street car after all, I most likely will not see the extra HP long tubes can give you with a serious engine build. But then again... HP is HP, even if it is just 3.
