    Pro 785 head to o rings anyone done it ?

    Was kicking around the idea of converting Pro 785 head ( stock) , to using o rings instead of the stock head gasket . After losing a cylinder to a lean condition , thinking would be easier to remove the head to check for piston wash , and o rings would be cheaper than regular gasket .
    Is this possible ?
    Has anyone done it ?
    Would a local machine shop be able to do this ?
    What o rings would use ?

    Been done before sure.

    Why not just get an aftermarket head with domes that already has it done?

    Or invest in a borescope or flashlight that fits down the plug hole so you don't need to remove the head?

    Get one of these.....

    http://www.ebay.com/itm/ProVision-18...-/230702328560 (this is a good price too)

    It aint one of the fancy ones like the Pro's use, but it does the job just minty!!!

    Or, go to the hardware store, WalMart, Home Depot, Amazon, etc. and get yourself a $9 flexible flashlight.
