Arc head


Dawg 89
It would think not , though my experience is with the Horstman Fire Slot head .
Where the plug is moved and also at an angle.
It is the finned head ? The un finned head probably would .
It is finned, But all I changed was the head and temps went up a lot. Maybe need to send micron back to get it checked. It did not feel or run like it was 528 degrees.

The CC of the chamber is considerably smaller (= more compression) so it SHOULD run hotter.
Rejet and time the thing for the increased compression and problem solved.
Hours spent on the dyno tuning helps too. ;)
