Considering doing this job myself [removing heads and sending them out]. My question is on the intake manifold,CD tells me how to remove individual parts from manifold.I would like a [step by step] removing only what is necessary to pull both heads.I have never done this type of fix before,so if you guys think i should bite the bullet and pay the big bucks please say so,i do not want to get into big trouble here. P.S I have worked on cars many times but to this length. THANKS
