I did a lot of work porting the cylinder head to make the engine rev so freely. The stock exhaust ports are originally are nearly square. The exhaust headers have nearly round ports and a lot of material had to be removed from the head casting to match the two. I also cut off the bottoms of the exhaust guides, although I do not think this makes a big difference. The intake is also port matched. I was a bit concerned about the huge amount of material removed from the head around the exhaust ports, but so far we have about 8 races on this engine and it has performed superbly. The brake lines on this GT6 are copper nickel alloy.
