Wow, this gets rougher by the paragraph.
Thanks Ken for the input. I have only seen pictures of the lumps.
Ok, how about seperating the "tounge" from the "gasket" piece. Shaping the tounge like a shoe horn or upside down spoon. Wider at the intake valve. Narrow at the port inlet. Bending the end, at the inlet, 90 degrees to stick out of the head. The part that sticks out and lays flat against the heads intake surface with a sort of puzzle piece lock into the "gasket" piece.
Next picture:
Just as another thought on the material to make this out of. What about aluminum or copper sheet metal? Easy to shape. Does it get to hot in the head risking melting? I have been checking out getting a sandbag and hammer for other body work.
Hammers going to need to be real tiny!
