My 1993 4runner has 190,000 miles and it seems to be time for a valve job. I have the 3 liter V6 engine. I plan to pull the heads myself and then take them to a machine shop. Can someone give me a list of the parts I will need to order?

I would like to have a little more power. Is there anything I can have done to the heads that will increase power without hurting gas mileage or causing me to fail the emissions test?

I have read that putting on headers is a good way to increase power, but that they are hard to put on the V6. Is this an easier job with the heads removed?
