SOME aftermarket intakes come with the exhaust crossover blocked out of the intake, thus sealing the opening on the head. On THIS 'Tunnel Wedge' there is no place, I can see, to 'block out' the heads exhaust cross over port.

The Tunnel Wedge came out in '68 as an over-the-counter, Medium Riser race intake with blocked heat riser. You just can't see it. I had mine on the original Medium Riser heads, and it's now on my Edelbrocks.
