Time Sert 5761E Big Sert kit, made by Time Sert in the USA. Big Sert means it's "over-sized" for use when a Helicoil or a competitive brand has failed. The 5761E is used in cast iron Chevy big blocks after a Heli Coil has made the hole bigger. It has a larger outside diameter but still accepts the original size 7/16-14 head bolts. If doing a first time repair the oversize kit is not needed, we recommend using the Time Sert 0761D.
