With the squish area being so small, the benefits will be less pronounced.bullheimer said:just to re-cap a bit. for this to matter in a head, you need to have quench, and the quench area is the flat part of the head where the piston will squish the mixture. this means that in my heads pictured here, where there is absolutely NO flat area, that using grooves would be a total waste of time right?
i didnt notice before, but there is no flat area at all to speak of. maybe a half inch at best, so i guess i'll just wait till i build a different engine.
