They look similar? But do they flow similar?
$165 to $225 USD (i got these a few months back for bare casting $165 plus shipping) DNA Motoring Heads off Amazon VS AFR's budget friendly 195cc Aluminum head
*Not a opinion just a comparison between them*
I don't know the longevity on the DNA heads as I haven't ran them yet.

*DNA heads

I didn't go into great detail on that in the video because I wanted to focus more on the casting and the flow as other parts can be changed out.

A big bonus with the AFR heads is they offer a great warranty! not sure about the DNA heads
*Both heads flowed @ 28hg, 4 inch bore, inlet radius and 4 inch pipe on exhaust

*update on a set of DNA heads*
Some port clean up and valve job 270+ cfm
