				Question for the Aluminum Cyl heads gurus?
			 
			 
			
		
		
		
		Ok I bought this motor (302) with aluminum cyl heads, however there is no brand name on them. It has the following stamped on the side right up the exhaust headers “57158-2” and on the passenger side real on the flat surface it has “A071”. 
 
I have been told the ends look like Trick Flow type ends.  
 
Anybody out there able to tell me based upon the numbers stamped on it listed above?
