I woulda never thought i would have to do headers first....what about the ubend first ? And since I'm gonna do the lim gasket soon should I be thinking about porting the sc?

Well you can, but lesson learned is that is a waste of money. All header kits come with pipes/adapters to get rid of the u-bend. So unless you just go to a exhaust shop and have them replace it any downpipe you buy to remove the u-bend will be pulled and replaced once you upgrade to headers. So you can baby step it and spend more in the long run, or just throw down the gauntlets and buy headers now and do it right.

And since I'm gonna do the lim gasket soon should I be thinking about porting the sc?

You can if you want. Won't hurt anything. Will lower outlet temps and and get you more flow when you pulley down, but you won't actually notice any difference just porting on a stock setup.

And you WILL need headers before you pulley down. Gotta have the flow mods.

Just make the left look like the right. Don't go out or up any, just bring the V further down to open the bottom. Make sure it's kept clean, shavings can ruin bearings and then you're stuck with a complete rebuild.
