SCE Athena 6-Bolt Head Gaskets w/ Stainless O-Rings 3.997" - .059"- Bore Right(CR199959R)

The ultimate sealer of your LS engine! Dyno proven to seal over 1900 HP without any leaks! Available in 3.997", 4.056", 4.150", and 4.174" bore sizes. These gaskets use a steel O-ring that cuts into the head to provide the strongest seal available for boost applications or high compression motors.  They do feature the extra tabs for 6-bolt capabilities.  If you are using them on a standard 4-bolt LS block, you can simply cut the tabs off that you will not use.
