hi all, the threads in the top of my cylinder heads (59 Connie) for the head steady brackets are toast...thinking of helicoiling them. My question is...would it be acceptable to use a metric helicoil insert as these are a lot easier and cheaper to purchase? Existing thread is 5-16 coarse I think, is there any benefit in installing a fine thread to help cope with vibration? Any tips/suggestions gratefully received. Richard
