I have a couple of places close by us that does the mil spec hard anodizing.they told me everything need to be removed before they'd put the pieces in their tank.
when done mil spec,,surface is hard to scratch.afr's h.a. comes off w/ a lite touch of a sand paper roll.

I'll check the sheet when I see the machinist tomorrow.
Maybe I'm goofed up on the exhaust flow as that does seem high.
According to the brodix site they flow 340 and 240 "as cast".
A local old timer that's been at this for longer than I've been alive does my stuff. He used to do quite a bit of work for the local shops before CNC came around.

I'll report back as I certainly don't want to give bogus info.

*edit* 313 not 330 on the exhaust. Also, 2.30 intake valve instead of the 2.25 the heads come with.
