These heads are looking less and less a great value or even just mediocre value including snagging them during a Black Friday sale.
Buying bare castings, your choice of valves, springs, retainers, locks, seals, shims, shipping cost, paying for the valve job, and correcting the saddles adds up. A geometry correction kit if you’re going to do it up right. Then the time and travel to acquire and get everything in the hands of the actual shop you are paying, the gas etc.
Other than buying them fully assembled and just running them OOTB on a lower HP build
OR
you have the ability to do all this yourself
it adds up to a “False Economy”
Forget about the porting it takes to get the heads competitive with other offerings.
Will anyone be so bold and brave as to actually add up the money and time invested it took for them to get a set of these heads ready to bolt on?
Seems it Just ain’t worth it.
