Dropped the motor out of the black 54 on Saturday morning, stripped it down and found the source of the scary noise that developed during the week - I had dropped a small washer down a carb throat while fitting the velocity stacks. Amazingly no damage done, but while it was out Lee at Kraftwerk ported the heads. They started off life as 42x37 CNC round ports and were then ported to a very good standard by the previous owner. After having considered a change to wedge ports and having had a look at a set I felt they could take a bit more porting still, so took them to Lee at Kraftwerk. Lee took them out to a similar port to wedge ports. I then spent what seemed like forever porting the manifolds to suit the modified heads. Have a look at the pictures for a before and after of one of the manifolds during porting - apologies for the picture quality but it was in a dark garage! The engine is now back in and fully built up but I didn't finish til late so have not started it up yet - tonights the night!
