Xflow Alloy Head and Heater

[WitlessEvil]

Hello All,

 

Does anyone with a xflow that has the weber alloy head have it drilled for a heater? Mine came without a passage from the water jacket to the intake manifold, although the indent is there. My guess is that it would be a common mod to block it off for racing just to keep manifold temps down, so the replacement heads don't even bother to complete the passage.

 

I didn't want to start drilling into the head without knowing that it is a least possible.
