Kb190 Pistons And Eddy Heads

Depends on where it is at right now and where it is suppose to be. I would imagine it is suppose to have 108 degree centerline. Move it to 110, it will give it more mid grunt than high end. Also recheck after that. I dont think 2 degrees either way is going to solve the problem completely.

Then when you see where you are at notch the pistons for more valve relief.

Every off the shelf piston i have ever used, seemed the valve reliefs were too little and alot of the times not even properly located.
