Can Old Heads Flow Like New Heads
			 
			 
			
		
		
		
			
			I have a set of 842 Aluminum closed chambered heads dated for 69. They are going on my COPO/YENKO L-72. I have the correct Winters stamped 163 aluminum manifold and correct carburator. Here is the question; I need to keep the correct heads and manifold for the authenticity sake. What can I do to the heads and maifold to get them to flow better and perform better. I would love to have a sharp guy put these on the bench and get them to flow like a set of AFR's.
