I'm not trying to promote what I'm selling, but for your engine setup, the Toomey pipe will be a good choice. That's why I'm selling it; I'm getting some porting work done and possibly a stroker crank in the coming weeks. With these internal engine mods, I need a right-bend pipe for best performance.
If you're looking to keep your engine stock inside for awhile, the Toomey will work well. If you have major engine mods planned for the future, I'd wait and get a right-bend pipe. My .02
