DING DING DING SOUND THE ALARM!...

That's right, I forgot about that. Good call. There's so many posts from last year, I wish I could go back and find that set of posts, because as I recall I wasn't able to find a part number for an assembled head with cnc chambers, but you had a set.

I saw the post where Porter did a some more seat angles on the cnc version and the numbers jumped closer to advertised.

People should be careful, like you said about the throat diameter ... big...too big. I do recall folks building with 190cc heads from various sources, hughes, bloomer and the outcomes were less than expected. My 1st instinct was to buy cnc versions bare...fix the valve job , flow test and run them. ..but my memory stepped in and reminded me.
I also expected more meat in the intake short turn, taller, there isnt much there.

Thanks to pittsburghracer and PRH, as well as all others for the work they shared on these. It laid down the approach/plan of attack for the rest of us.
