954RR's maybe? If not, what size?

I called several weeks ago looking for the optional sides but you were out on a run...you know anyone with a pair laying around?
Headwork is the single most important aspect of a naturally aspirated engine Jason. That's what I meant by it. You can have all the compression you want, static or dynamic, if you can not increase volumetric efficiency with the head, then you're going to be limited by what that head can do. Now forced induction need not apply in this case of course because volumectric efficiency is achieved using an external device. Ever wonder what separates a non-vtec engine from a VTEC engine? The head is the single most underlying factor in power delivery difference.

The ITBs i have here are for 1000cc motorcycle. Wanna take a look at them?
