    the rockers came shipped to me all wrapped up in newspaper because they were used. I can't tell which ones are the 1.8 and 1.85, other then a small pin hole at the top of the one on the left in the picture. the 1.85 needs to mounted above the spark plug and 1.8 above the exhaust so its kinda important.

    If I had to guess i would say the one on the left is 1.8 and the right is 1.85. You can clearly see a lil difference between them but idk man. Too bad the person before didnt seperate and label them.

    Flip them upside down and look where the pushrod goes on the rocker. The ones with the dimple closer to the trunion are higher ratio

    They are not etched at all? Mine had a light etch to tell them apart.
