Missed on this combo?

Is it possible, that the valves you tested with, are different in some way, then the ones that ironmike used?
Them numbers look grate to me and so did the SSR. (Said the educated idiot)
What do you think of ironmikes cam?
I know i should just stay out of this conversation at this time and let the smart ones speak.
But curious and want to learn as this all unfolds.
I don't pay much attention to flow numbers any more. (Although i always have to know)
I just did this as a base line from when I did prototype.
I am not a fan of stock location rocker on the head. I really did the offset head as my main goal but Mopar people want the no offset deal.
The head has some noise on the flow bench and I don't like that I think some of that is in valve job.
I am like Rod I that I don't like that they did not make the same or more power than the other heads but I think the engine is down on power due to more than just a cylinder head problem as both sets are "down" from expected numbers.
I am not a fan of the cam choice in this engine at all.
Rods heads where run with all but .5 point less compression than the other set not a huge deal but less CR will not add up to an engine that makes more power. Add in the fact I do not believe the cam is filling the cylinder efficiently and that will show up in lack of torque real fast.
The min square inch of Rods heads at pushrod is only 2.1" not a deal killer but everything has to be right to make small cross section work on 408" engine.
I think Rod wants to tweek on that part of the head and I will play with some valve jobs see if I can make head little better.
The end of the intake was opened up to match up better with Rods heads. I wish I would have been asked about if this should be done or not. I think this hurts intakes don't like any cross section change going larger right at flange of head.
They responde much better to taper all the way to the head (most of the time on lower RPM/power engine it works better with end of intake smaller than the head)
Air speed at .600" lift was 315+ down center of port and in the 380s at the short turn far from a to large lazy port IMHO port is still way to small for 400" plus engines.
I will update with what we do moving forward.
