Drivers Side Rear Spark Plug 440

I am not sure what the last guy had going when he welded those in, but he had a 440 with a 6-71 blower on it. My dad being the original owner made his own when he put the 440 in, but not these. I have been merely comparing pictures of other's set ups - valve cover to master cylinder, heater box, wiper motor, etc... To me it looked low also, but how low can it be? Maybe just enough. I had thought of cutting them all out and putting elephant ears in. I do have a spool mount K member that could be swapped in with Schumacher mounts, but planned to save that for when the day comes to go back to a 340+6 and factory inner fenderwells.
