mopar mpi upgrade question.

I have searched and can not find anything, I could call HESCO but thought I'd ask and get advice from people who have done this upgrade. I have an 85 cj7 with power brakes. My questions are:
- I have Clifford headers, will these work with the swap? I know I have to weld in an 02 sensor bung.
- Will the intake assembley clear my brake booster? Right now I have a Clifford intake with a holley 390 and it's really close.
- Any issues with my valve cover? I have a Clifford aluminum one. With a push in breather in the front and pcv in the rear. Any issues with using the valve cover?

thanks!

Also none of the emission hoses or canister is there. These were gone when I got the jeep. Thanks.

I was able to install a Borla header, but it required some modification to the power steering pump bracket.

Also, no power brakes, so can't speak for that.

The intake manifold clears the brake booster by about an inch. However, the Manifold Air Temp (MAT) sensor attaches to the manifold just below the booster. The top of the sensor clears the booster by about 1/4". When you need to replace motor mounts in the future, you'll need to either remove or relocate the sensor to avoid crushing the sensor. With multiple plugs and sensors on the manifold, you can use the locations that work best for you.
