    Description

    3927186 are good heads if you want high compression. They are 64cc and will give you 10.3 compression with flattop pistons.
    They did not come with hardened valve seats so they are not good for unleaded gas unless they have been modified. Also, most of the 186 heads were 1.94 valves.
    Machine work done:
    Modified: Exhaust hard seats, surfaced, new guides, boss machined for screw-in studs guide plates.
