414 Dyno results: Missed combo?

IMO, you are about .100 short on lift, and the headers are too small.

That's why VE is up at low RPM and then falls.

That's what I'm seeing at a quick glance.

Also, maybe the IVC is early for the displacement.




Edit: wanted to mention the BSFC looks pretty good thought the pull so the tune up was pretty spiffy.
