Quite a difference. Is 230F + too high?

Buy three extra sending units if you want feedback jn all 4 cylinders. This will give you much more instantaneous information as to head temp changes. I only needed one senderon the #3 stud on my old 79 Loaf, but I could certainly tell when I was climbing a long grade and when I was off the throttle going down!! It would hit 450 F t the top of the hill and drop 100 degrees o nthe way down. The water cooleds prolly don't change that drastically, but kep in mind you're not using a $1000 pyrometer to do the measuring. Use the numbers as a "Point A, point B and Point C" and compare everyday running temps with high and low load readings. If things get too warm or too cool, THEN some detective work is in order. I don't have head temp senders on my water boxer and prolly won't unless I win the lottery. YMMV DM&FS
