Currently working on a 1985 Evinrude 150 (E150STLCOH 1985), and i recently found out that the STBD head needs replacement. I have a line on parts from a running 1988 Johnson 150 (J150TLCCA 1988). Will the cylinder heads from this engine work with my 1985? I believe it will bolt up no problem but I'm no expert on compression numbers. Its either this or i but a new cylinder head from ebay.

Thanks in advance for any input!

There's a part number on the head (raised numbers), usually in small numbers somewhere near the top portion in circular form. What is that number?

The part numbers for the two years are not the same. That doesn't mean that it wont fit. OMC had a habit of making minor changes and the part numbers changed accordingly. The part number you need is 329773. Try Ebay for that number.
