Before jumping in with both feet, make sure you can put your hands on a matching head and pistons. If you plan to re-use both your head and set of pistons you should have no problem. But if you need to replace either the head and/or piston set be advised that 228 engines used pistons that were domed on one side of the top, domed across the middle of the top or (not shown) flat top.

The first picture is of my '52 228. The 2nd picture is of a 228 piston that I do not know the heritage of.
