Vac. Block Gasket?

[BFlat]

I have an aftermarket vacuum block with the extra port for vac. brakes. Is the gasket between the block and the intake different from stock?Thanks.

Should be the same gasket

Should be the same gasket

It is, and why would it be different? The pattern on the throttlebody doesn't change because you've replace the vacuum block.

This (attached) is why I asked. Same block - different gasket.
