Bad cylinder head?

I just compression tested my quad and the front head was 180 the back 160 and leaks about 5 psi the back head has a brand new head gasket. It overheats and shoots antifreeze out of the overflow. No antifreeze mixes with my oil and my plug looks brand new when I pull it even though it’s been in for a bit. would this be my head?
