AFR Results
Recap, I ordered and received set of AFR 210's from AFR in ~7 weeks. Took them to local machine shop for some hard facts.
.100 65 51
.200 131 106
.300 194 143
.400 240 175
.500 270 202
.550 276 213
.600 279* 218
.650 277 220
.700 274 223
Intake and exhaust respectively.
Chambers were 76.4 cc
Intakes were 207 cc
Exhaust were 73 cc
Valve seal checked ok.
Overall, I'm very happy with the results. Both intake and exhaust are very close to as advertised...I've heard AFR was quite optimistic in their claims. Also the valve seat seal was right on.
Only complaint is they weren't very clean. Aluminum shards here and there, but probably not decisive on a hot rod engines longevity (mine will blow up before it wears out :))
Anyhow...I recommend them...course the chassis dyno will tell the tale, but I have nohthing to compare it to.
:D
Sorry mistyped the .600 lift...correct number is above. Solid head flow...:)

Re: AFR Results (VETDRMS)
It's interesting that the .600 spot fell off, I wonder what the reason is behind that :confused: ?
I'm waiting for the same heads and my mech roller cam lift is .616/ .622 so the .600 number wil probably be an important factor for my engine.
I wish they would advertise on the conservative side :rolleyes: .
That said, I can't wait to get mine together and go for a drive :D .
