There are insulators to encompass the notch
I would contact PMO for a set. Bruce |

Thank You You've brought something to my attention. The heads I'm working with have a hole that extends from the top surface of the head directly into the intake port aimed at the valve. It is a ~14mm hole, not a notch. The hole is smooth, not threaded. |

On the 2.4 CIS heads, you can run a tap into the hole and then plug them just like you do with the MFI heads.

Tom hit it, the 73 CIS heads had a pressed in aluminum sleeve where the MFI injectors went.
once removed, there is no threads. That was an only year application. Bruce |
