oh thanks didn't know about those valves. I choose that engine because of the cam sensor but I also have a vr4 head sitting in my shed that I was going use at some stage as I have got some 1680 injectors and 272 hks cams to help make some decent horse power once im happy with how it all runs. the gearbox is just an early l200 unit but I have a couple of little tricks use to try and extend the life of it as I have been told that will be the weak point
