I need to remove the passenger side head and put it back. (engine never started since install) I'm using the factory GM plastic/rubber (or whatever they are) Vortec gaskets. Can they be reused? I am also guessing I can reuse the GM Vortec intake gasket?

I was assembling my TPI Vortec w/SD intake and realized I needed to take one of the heads off to tap a bolt hole since the L98 heads have an extra exhaust manifold bolt.

thanks.

 

Intake gaskets- yes, they are reusable, especially if the engine has little or no run time.

Head gaskets..... maybe, since you didn't run the engine. See how they look when you disassemble. If there's any tearing or lifting when you pull the head off, they're toast.
