Exhaust scavenging and head porting
#1
For those of you that have ported out your heads, did you match tot he exhaust manifold. The reason I ask is that most theory tells us that a small lip at the port is good for keeping down reversion into the combustion chamber. We don't run that much overlap on the stock cams, so will it really make any difference. If it will how much of a lip did you leave?

MY old XFlow had a slight lip on one port (but I thought that was an error)
The new one Dad and I just fitted is a perfect match to all gaskets(and quite a bit bigger )
will see if I can post photo's
