I use the same method.
Those books don't always tell us right every time.

I had buyers for 061 heads after the HPP flow test articles, and kept a look out for them.
Only ever had that one set on the XJ engine.
73-74 #46 heads with screw in studs from 350 engines got popular after those articles too.

Are 061 heads worth anything these days? I always thought they were not high performance because they weren't the 067's. I believe both are closed chamber. Is the difference the same as a #13, #12, #62, #48 heads, or maybe the 68 #16's?

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.

Thanks. I have a set of 061 heads I was going to toss. Shipping them may cost more than they're worth.
