Intake Manifold Question

Sorry to revive this dead thread but I need to install my intake again. Did a whole front end rebuild and cam swap.

Does anyone know if I can use a beer can aluminum to block the heat riser passage?

Get the proper gasket with the block off...

If you use the wrong material, it will burn through...

Even with the right material it may also if not installed correctly...

We put an engine on a dyno with one exhaust crossover flange gasket torqued properly, and one that wasn't... The one that wasn't torqued properly burned through, the one that was didn't... That proved that you had to have the joint tightened properly for the gasket to survive that heat/environment, even with the proper material...
