The RMC "glass head" is a unique head that allows you to see inside the cylinder, even while the engine runs. Using the right lubricating oil, it will stay "Windex-clean" (crystal clear) inside the cylinder indefinitely. The RMC glass head is a proven design but like everything it has limits. For safety, it’s only to be used on lower compression engines.
Simple machining plans for the glass head along with pre-cut glass stock is $10.

Note: The RMC head is meant to use with RMC's 7/8" bore engines. The information in the machining plans can be easily modified to make the head & glass stock adaptable to most any engine.
