    03' OX66 200 HP (Upgrades)

    I've for a 2003 OX66 200HP that I am planning to rebuild. However I am wondering if there are any reasonably priced upgrades that someone could recommend? I'd like to boost power if possible.

    Does anyone know if the JTM Out Board shaved heads are as good as the Hydro-Tech heads? JTM is about half the cost.

    a shaved head is a shaved head, IMO. Are the JTM new, or used that they milled? HT will be brand new parts.

    I think JTM will use my own head. The HT kit will have the head and the matched head gasket. If I'm thinking clearly the heads are shaved but if the head gasket is not at the correct thickness then the compression numbers will not be the same. I'm going to do my own calculations and get a better understanding of the details.
