    Will be watching this one as well. When the times come for a top end job on the WR300, I'd like to have head and porting options. Would have liked to have a factory race head, but those have long been gone.

    I did. Those were ported for MX and race gas if I remember correctly. For the kind of riding I do, more top end isn't really what I'm looking for.

    Yep, I think we talked about that. They are Pro Circuit ported. Good looking with low hours though. For us mere mortals who don't ride pinned all the time, they are a little overkill.

    However, Ty might know where to go for the custom porting work you are looking for.

    John Kearney/Ajax Auto has a newly re-lined cylinder and head for a WR300. I know because it is in my office. If you are interested in those parts contact John.

    I also have a WR250 big bored to a 300. It uses standard Gas Gas EC300 pistons. Ported for bottom-end and pump gas. It's a serious beast.
    Comes with a machined head and main (power) / side (booster) valves and a piston. The bore is still in perfect condition. Has about 2 hours on it. I just want it out of my garage. So I'd be willing to let it go reasonably cheap.
