My Hondata Thermo intake manifold gasket used no other sealant, Hondabond or other. And it ran a coolant passage through it, with no problems.
I did however re-torque the IM nuts several times after it had been heat cycled. Eventually they stood up to the factory torque, but took about 2 weeks. So just recheck the torque a few times after the install.
What kind of throttle body did you swoop?
