Combustion chamber - before & after

Here's the before and after combustion chamber view. We've opened up the inlet valve shrouding, as well as shaped the wall to be sloped and curved. We could have opened up the face leading to the plug a little too, but it's not supposed to be a track car. Quite a lot of material removed, as you can see on the work bench, with a little more to come off next weekend when we smooth and polish it a little more. Overall, pretty pleased with our first ever head tuning…only a dyno will confirm if it's been worth it!
