Why take off the rockers to remove the cam? To take the intake and lifters out the rockers need to come out too. At least that is what I thought. On RTV, yep I do the same around the H2O ports, head side only.
Update and bad news on the progress: One of the stainless steel inserts for the rocker bolts would not take a 40 ft-lb torque (the one with the
oil hole). Long story short that head is off to Shelby to be repaired, no charge (thanks Shelby!). Also swaping the bolts out for studs which they should have been in the first place I am learning. Good news is that the head came out with the engine in the car as luckily it was the passenger side.
