BTW - Permatex Ultra Copper is a good RTV for the exhaust VCs. You'll also need a little dab for the intake VC "corners". That is, any place where the VC surface changes direction to go up/down (over the CAM ends or VTC solenoids). You'll also want to remove and reseal the VTC solenoids.
Clean up prep is the worst part of this job....takes a long time remove the old hard sealant.
