Our Hemi Spark Plug Tube Seals are designed to prevent oil from entering the combustion chambers when the spark plug tubes are removed. They are made from anodized aluminum and fit most Gen II Hemi cylinder heads. Machining is required when using aluminum Mopar/Edelbrock heads. If you are using aluminum Mopar/Edelbrock Hemi heads, nobody’s tube seals will fit. However, we do offer machining services to accommodate these helpful Tube Seals.
- Sold Separately
- Labor to machine cylinder heads : $95.00/set of heads
