Looking to get some more bolt ons

Like the title states I can't find a lift to put on the headers I bought and I don't want to pay $500 for a shop to put them in. So I'm guessing I'll just sell them and put that money towards boltons I can do now. I've been looking at rpmoutlet between a Professional Products tb/C&L plenum for 200 or Motoblue pulleys(which aren't piggyback). They even have them both in a package deal you can buy for 350. I've heard mixed reviews about PP and motoblue. I've also looked at the Granatelli coil on plug connectors for 90. My goal is to reach the 300rwhp mark N/A without spending too much, and maybe using nitrous in the future. I know I won't be able to reach those #s without headers so I guess they might have to wait for later. What would you guys suggest?

I'll probably end up doing the header install later, even though I was gonna pay someone else around 175 or 200 bucks to install them, he just said he needed a lift. I just found out that my friend's boss can pretty much get me things at summit racing and most other places for half off so I'm leaning toward a tb/plenum or electric water pump. It's still hard to pay for a tb/plenum when modular depot only got about 4.5 hp with a trick flow plenum and 75mm tb. BTW the guy that owns the racing shop where I get my parts installed (who only works on modular mustangs) told me that piggyback pulleys were junk. Thanks for the input.
