Extra cooling fin on Type 4 cilinderhead.
			 
			 
			
		
		
		
			
			I've seen Type 4 heads with extra cooling fins welded onto them, but have no hands-on experience with them. I'm still wondering how this can be done because every Type 4 I've built had no room at all for such an extra fin between the head and the cilinder.  
Anybody? 
 
Thanks in advance!
