Ive always been rather amazed at the amount of work good port work requires,
And yes it takes tools experience and knowledge so its not something (JOE AVERAGE) (can do well on the first try)
and as an a guy with an engineering back ground, I could never understand why , (AS A CYLINDER HEAD CASTING COMPANY)
once you find something youve modified is close to ideal,
you as a manufacturer, don,t simply change the casting core to duplicate the physical config,
so that you has an as cast port or head combustion chamber that's close to ideal without having the time consuming individual port work required.
after all doing so makes the cast cylinder head you sell, vastly improved over the factory OEM HEAD CASTING,
making all the OEM PREVIOUS castings basically obsolete junk.
this is why places like BRODIX have a large selection of aftermarket head designs that may fit the factory block,
but require new pistons, intakes etc, because the OEM was much more concerned with ease of manufacture, low parts cost and ease of assembly,
parts that increased durability or increasing power at rpm range the original engine would never be operated at were not a prime objective

example the 18 degree heads for the BBC engine, they massively out perform the original BBC heads and don,t use the compatible intake or any other part, but they do fit the block, no factory engine would ever be built to use something similar due to much higher cost

I agree and disagree with you.
Many of the Race World Famous Cylinder Head Porters have sold thier work to be CNC Duplicated and even more have had thier secrets stolen.
Advanced Cylinder Head and Intake Porting I observe differently.
It allows you to custom tailor to a particular engine combination.
Just can not be done with off the shelf parts alone.
Once you learn the basics if someone copied your work it's not end of the world your done.
Literally hundreds of different Porting strategies.
Most important is the port shapes.
I don't see Factory cast iron Pontiac heads as Junk.
They are all sleepers that can be improved by a huge margin.
They have the advantage of 100% USA Iron used no China any.
Also have excellent oil Return back to the oil pan fast. It's a huge issue on many Aftermarket Pontiac heads I learned we never knew about here in past.
Best way is external plumb #8 & #10 AN oil return lines back direct to the oil pan many Aftermarket Aluminum. Was kept secret. Still is .

Big Block Chevy has huge potential Porting Factory iron.
Its supposed to be one of the hardest most time consuming because the Runners are so long.
