These cylinders look virtually identical to the O.E.M. and are available in standard or big bore sizes. Honed to exact size for easy piston installation. Big Bore cylinders do not require machine work.
Great drop-in fit with high-quality name-brand components. The boost in displacement is welcome but isn't so big that it's going to stress rod or crank too much.
The included gaskets can all be used to maintain the compression ratio or separated to boost compression ratio. For this you'll want to measure the old parts since the instructions don't mention it.
