I would look for another bench too. Either that or someone forgot to screw a spark plug in the spark plug hole. Lol. That’s the reason way I always flow and give before and after numbers.
I did have them flowed a year or so ago (same bench but possibly different operator and conditions idk)after opening the pinch a bit and some quick clean up. Not sure if I still have the numbers saved somewhere. The port seemed pretty fast. If I remember correctly they were like [email protected] but didn't leave the 250 range from .500-.700. So I brought them home with the idea that I would open the pinch a bit more, try and slow them down a bit and play with the short turn. The exhaust #s were pretty typical so I went through them again as well. I was expecting no more than mid 270 on the intake and maybe 200 for the exhaust. I'll figure out what's goin on this week.
