S&S Compression Release Hole Plug

NOTES: S&S rocker covers must be used with electric compression releases due to clearance requirements for the solenoids. Rocker covers must be removed when installing S&S® compression releases. If lack of frame clearance prevents removal of rocker covers, engine must be removed from frame for compression release installation. In most cases, S&S compression releases can be installed while the engine is in the frame with the special S&S two-piece socket kit, part #53-0045 . If cylinder heads are machined for S&S compression releases, but compression releases are not used, special plug part #90-4916 (two required) must be installed to seal the machined hole. Stock cylinder heads cannot be machined for S&S compression releases because there is not enough material in critical areas.
