Do Schumacher slant six to 340 motor mounts raise engine?

I didn't read thru the complete thread, But:
The "spitfire" headers that layson sells you need to specify factory mounts or Schumacher mounts. The headers are different. Also on the 66 down "A" bodies Schumacher brackets allow use of the 6 cyl drag link where the factory brackets require the use of the V-8 (larger drop) drag link to clear the oil pan. So, Without personal experience, I am assuming the Schumacher mount raise the engine somewhat.
