hi guys doing a bit of head porting if anyone has seen the pics, just want to know whether its a good idea to remove the part of the valve guide that protrudes into the port? ive read a few articles saying to remove it so its flush ???
im basically just port matching, turned the head into a 4 port instead of 8 and smoothing out the inner radius to the valve.... is actually quite a extensive port job now i think of it.
