Can anyone tell me if these heads have been modified and/or why they have a little 'step' bored into them? The first picture shows a 'normal' head. Notice the flat surface shown circled.
These next two pictures are the heads in question. Have these been machined/modified in any way? If so, why? Thanks, Rob |

The one middle picture looks like they have cracks at the plug holes going in opposite directions but don't seem to be bad enogh to fix unless you want them perfect.
(IMG:style_emoticons/default/beer.gif) Nice and clean though and wondering about the combustion chamber size of the cut one and if it would increase the compresion slightly if they are smaller? Are you ballancing these heads yourself? |
