Factory Aluminum Head Intake Seat
			 
			 
			
		
		
		
			
			I’m hoping someone has some insight on this. I have a 68 BBC aluminum head(3919842) that has a damaged intake seat. I’m wondering if anyone knows a source for an exact replacement for this seat or a NOS seat. I don’t want to machine oversize and that is what the machine shop says is necessary do to current availability of parts.  
 
Thanks, 
 
 
Jason
