FYI, my stock engine runs 150-170 depending on time of year. Had it out the other day in 40 F and temp was about 135-140 max.
Are you running straight water or with some anti freeze (curious) I have a laser temp device gauge from O Reilly's, the upper 1/3 of radiator runs about 10-15 warmer than the bottom half.
When on a tour with the group I always bring the temperature gone alone and shoot their rad temps when we stop. Most are around around the 160-170 temp.
If you are using straight water only, I would suggest maybe using Water Wetter in the rad, just my suggestion. We had a chemical engineer give a talk at one of our tech evenings. His thinking was straight water in the summer with Water Wetter and half anti freeze and water in the winter. Our club is in Canada, hence the anti-freeze as a precaution.
