Hello to all that have replied.  I really appreciate your responses and knowledge  I will sonic test later this summer.  I Have to finish a 425 buick nailhead first.  If anyone is curious I will post the wall thicknesses when I do that test.  Again, thank you all.

Thank you Blair!

I have seen similar comments from heads that my brother ported. The customer complains that all areas of a port are not "finished".
Many do not realize that some as cast ports are already too big in certain areas - hence not being touched.

The heads are cast with throat sizes that will accept 2.09 and 1.600 minimum valve sizes.  I have different programs for various valve sizes.  We run the cnc through all intake ports, on every head that is sold, just to touch up the port and keep the product consistent.  There is no worry of “core shift” when we do that.  There are areas that do not need to get any bigger, or be shaped any different.  Making the hole bigger isn’t necessarily better.  All of the transitions from cast to milled are blended nicely.  The places that need to be bigger, are such.  A lot of testing went into the port shape and design.  The cnc work that is done is done with results in mind. Making it bigger just so the program cleaned up completely would actually hurt more than help.  The poster might want to put those heads on an engine and test them before he gets too bent out of shape.  Might be surprised by the results if the rest of the engine is up to it.  He failed to mention that the valve job is perfect, and the blending from the seat insert to the cnc milling is also blended perfectly. 

To the poster:  If you are not happy, and you want to return the heads directly to me, I will refund your money in full, provided they are unscathed.  You will not be able to buy a better head for the price paid with better quality hardware, with a Medium Riser port location, than the head you just received.  I’ve been doing this a long time, with some modest success here and there.  That is high quality stuff you have there, whether it is obvious to you or not.  There is $800 worth of tool steel retainers, machined 10 degree locks, PAC solid roller springs, locators, blue Viton seals, shims, etc. included in that price you referenced. Again, if you want to return them, get in touch with me directly.

The real question is, why are we just hearing about these bosses and why no pictures and dyno videos?😂😂
