I noticed that I have a slight oil coming from the manifold near the oil sender. I noticed a small trail of oil down the block between cylinders 5 & 6. I also have a small exhaust leak here (fixing it today). Is the oil leak an indicator that the head needs to be retorqued?

This engine has about 1200 miles on it after a rebuild - should I retorque the head?
