    Default 20e cylinder head!

    I've noticed on the head someone has cut grooves in the head where the valves are. Any ideas why this would of been done. I took it to road&rally today to get it checked for flatness incase it needed a skim he said never seen it before and dont know why it would of been done.

    After a bit of research I believe these are signh grooves to help with combustion! Anyone know if it helps or best looking for a new head. It's a new head by the looks of it for a c20ne turbo build iam doing.
