I try to tell people this, but Hughes and other big namers post flow numbers from miracle castings that have 7angle valve jobs done with proprietory cutters.
If you search on this site you will find threads with stock la head numbers that are way better than these, and with a smaller 1.88 valve.
Both tests of those factory smaller valve La heads flow better than factory magnum heads.
Thank you op for not only sharing your build , which is pretty cool btw, but also giving non biased independent information. These are the numbers most of us non famous operators of a flow bench get with ootb magnums.
No doubt that when you get done with them they will flow like they should have to begin with.
I'm not sure why Chrysler chose to produce a head thats ahead in the stem size, chamber, and exh port department...but cripple it as cast with that crummy int port...its like they just reversed the good intake bad exh.
