Ahhh your a lucky guy :B
DW car ( Infiniti FX45) you have to pull off the valve covers to get to em. I don't understand the complex theory the manufactures now have, other than keeping the dealers in business.
I must confess though I had a 69 SS 396 which I added Hooker Headers to. Dang didn't think about that 7 hole at the time ( Young and dumb). Well about every 1500 miles or so it needed new plugs and yes you guessed it, we had to remove engine mounts and jack it up a couple of inches.
Needless to say I was sure glad I was a kid working for a good old fashion gas station, you know one with hoists :W
Good Luck buddy
