Project86- My first (and probably not the last) Rebuild

Are you using 6-port housings for your NA build?
I misunderstood.
I want to build a 6-port for power some day, but the secondary ports close too late with the sleeves out and flow too badly with the sleeves in. The 6-port is a lose-lose. You can get relatively good low end, but the high end is terrible, or you can get all high end and no low end at all. funny that this is exactly the issue that it was intended to fix...

I still wish you the best. What intake manifold and carb setup did you decide on?
