Setup Suggestions, input greatly appreciated!

I like the HD Wiseco's, but man it is serious overkill for your setup. I don't really know about the Manley pistons but they seem affordable and may be worth looking into. ExtremePSI shows them in both 8.5 and 9.0 ratios. I personally would go with 8.5 because I feel it will only assist in making tuning simpler, and well if you want more power, just add more boost! I personally run Mahle's which are very nicely priced, are hard anodized, and are one of the lighter pistons available off the shelf for our motors. But they seem to be more prone to cold start up piston slap due to being made from a different material. And their skirts are slightly shorter so I've wondered if that would affect longevity. But I've been rocking them for nearly 5 years now I think, and they are doing fine.

Is there something wrong with the motor, because really it seems like the money spent building the bottom end could be wisely spent elsewhere since you're going to be on a 16g setup.

As for the head differences. I personally feel the 2G head is a better design. The smaller ports allow for higher velocity, and the angle the intake ports take towards the valves is less extreme. If you have a way to simply clean up the casting on the intake ports, that's about all I would do. I wouldn't mess with an extreme port job, or 1mm over valves at your levels. Once again, money could be spent wiser elsewhere.

Everyone will have their own opinions, and it's your choice in the end to decide what is best for you. Good luck with the build!!!
