thank you all! @siren676: nice result! @nastyrash2003: ist a 5e-fe head with the 5e-fe camshaft, i havent seen any difference betwen it and my 4e-fe head. the compression ratio is now about 10,3 : 1 i didnt do much work here some more pics: before after and i make the gasket fit better, this is how it looks before the dyno result is not very good because it runs to lean, now i mounted a fuel pressure regulator and it is much better
