I have been involved with dozens of engines that have this modification. Never have I heard of a problem, all positive. Improvements in combustion efficiency are very different from improvements in volumetric efficiency, more difficult to quantify. Expect improved idle, throttle response, cleaner oil & plugs, reduced fuel consumption, less detonation tendencies and more power.

Here’s some pictures from Bart Jr.s Nova, he made a final round appearance at the Sports Nationals at No Problem Raceway. Piston and head pictures are after plenty of run time. The incredible part of this story is the car is no E!
