An internal combustion engine having cylinders and a head assembly adapted for compressing gas, wherein one or more cylinders of an inline-cylinder engine are modified to compress flammable gas, such as natural gas. The engine cylinders and head assembly are adapted to compress gas by: modifying existing engine valves to secure compressor intake and discharge valves within the head assembly; converting engine pistons into compressor pistons; inserting filler plates into the head assembly; and replacing the engine manifold, which is in communication with the adapted cylinders, with gas intake and discharge manifolds.
