Cams: $525
Springs: $200
Gaskets (Front Cover, Upper/lower Intake, Head, Header, Valve Cover): $150-$200
Heads (mine were Patriot w/no core): $1295
Head bolts: $50 (headbolts.com I believe)
Labor: $800 - $1000 depending on shop.
If it's a Windsor (99/00) motor you'll also need cam bolts/spacers & sprockets: $80-$100. If it's a Romeo (01+) you won't need these.
That's all I can think of at the moment, so you're in the $3,000 ballpark like was stated.
