Just set aside some time and put headers in yourself. I paid when all said and done around 350 dollars for my speed daddy header install (this includes napa easy seal band clamps, copper rtv, pipe expander, etc). An intercooler is going to cost you more.

Just do reading before hand and know what to expect and deal with it.

Even if you intercool I guarantee you will come crawling back to wanting headers to drop yet another pulley size.
