Holy ****!!! 
AFR 205 heads flow numbers
AFR 205 heads flow numbers my AFR 205 heads are almost finished all they need is just assembling the valves, springs...etc. i purchased them bare from AFR and got them hand ported only by race-prep. i think the flow numbers are great compraing to the runner volume they will be so good heads 
, here is the info :
valves : 2.05 intake, 1.60 exhuast.
Intake runner CC's = 209.5
Exhaust runner CC's = 85.5
Chamber CC's = 66
Intake flow figures: Ehaust flow figures:
.050--36.3 -23.8
.100--77.8 -51.4
.150--115.4 -85.3
.200--138.5 -115.0
.250--171.2 -146.0
.300--202.9 -186.8
.350--230.9 -211.3
.400--255.3 -228.8
.450--270.5 -243.9
.500--288.0 -252.3
.550--302.0 -259.5
.600--314.0 -263.2
.650--321.1 -267.7
.700--327.6 -271.9
what do you think?
i'm happy the runner volume is so small compared to other ported heads.
do you think i better go with NA 408 with a big cam ( the custom cam specs for the 408 are 263/263 0.667"/0.667" 108 LSA )
or
i better go with iron block turbocharged or supercharged 365 engine ( 0.030" overbore)?

mike c, Bryan @ http://www.race-prep.com did the work on the heads.
Nate, they charged me $1450 for porting, $1560 for bare heads from AFR and $500 for the parts.

Damian, i'm not sure if the exhaust flow numbers with a pipe or not i have to ask Bryan @ race-prep.
so do you think i better go with a 408 engine with these AFR heads and this custom cam 263/263 0.667"/0.667" 108 LSA
or
i can make more power with a twin turbocharged or supercharged iron block 365 engine using these AFR heads?
