Phil, the car looks great,
I prefer the old cam cover, the new style one looks unfinished if you dont put the cam pulleys cover back on as the flange behind is visable and too bulky. the old cover and the machined arealeaving painted lettering adds a level of sophistication and attention to detail, whereas the flat lead cover and cosworth sticker look cheap and added on (not detailed)
Does the new cover allow the use of readily available turbo hangars?, Looking at it the bolt spacing is quite far apart thus the hangar may be awkward looking (if your using one)
Cheers JP
