They had good flow numbers for D-Port .
Home porters and home builders wanted them.
They didn't bring as much as 67-72 screw-in stud D-ports , but they weren't even sellable at all before the HPP articles.
Going rate would have been 150-200pr .
250-300pr for 67-72 screw-in stud heads. Back then.

1970 intakes got popular , and #46 350cid heads -also- after the articles.

There aren't anywhere near as many hands-on guys now as there were back then.
Paying to port or fully rebuild cast iron heads now is a diminishing return compared to box stock aluminum heads for non-numbers cars.
