heads and cams ???

it is not going to be that diffenent in skill level. same job diffenent timing and valve ajustment technique. Just read some info on timing and valve adjustment. It seems pretty strait forward to me. I am going to be doing the same thing. way to cheap to pay someone to do it.

here is some random info I have found on the 4.6 I found

here is an artical on timing

my take on it is just make sure you roll it over by hand before you start it to verify you have done the timing right since it is you first time.

here is a link to torque sequences if you don't have then already

my advice would be just to make sure you don't have to have your car done in a day or something make sure you give yourself some extra time incase the learning curve is steaper than it looks.
