Looking at a 1954 Mercury Y block 256 CI short block for sale locally to save for a future project. I've never messed with a Y block before and since this is a first year engine that will need heads, etc. I wondered if later year parts are interchangable. I'd hate to get it and then find out that 292 - 312 heads and other parts would not bolt up. My guess is that later parts will interchange but wanted to ask the experts before I drop some bucks on this short block. Thanks guys.
