cylinder heads dart vs. afr
so far i have found that a 205 afr head can produce 37 hp on a stock ls1
I havent found anythink on the dart 205 head but specs are very similar
on the arf it has a 66cc combustion chamber size and the dart is 62 cc, doesnt this mean more compression whick turns into even more hp if all the other specs are the same, valve size, cnc machining, intake port volume, wouldn'r the dart head prove more power
plus a set of arf are $2200 and the dart are about $780 a peice in jegs catalog.... you do the math

good heads for the price. few minor issues like the rocker stand guide notch has to be ground off, so it'll sit flat and not break.
yes, the 62cc will net a little more power.
i have personally seen the AFR heads produce 37 rwhp on a completely stock 2003 corvette with no tuning. it's a test that vinci did for AFR. the car was completely stock as from the factory. swapped heads only, nothing else and picked up 37 rwhp with no tuning at all.
i haven't seen any other head company do that kind of test.Cold Air Intake, Muffler Delete, Vinci High Performance Dual Valve Springs, Hardened Pushrods, Yella Terra 1.85 Rockers, Some Hydropdipped Stuff, Strut Tower Brace, Some SS Badges, boost/vacuum gauge, fuel pressure gauge, some checkered stripes, drilled/slotted rotors, ZL1addons Stealth wickerbill, Ruxifey LED side markers

math says $60 per HP on AFR
if i was young and dumb again i woud probably spend the dough, now I won't even though I could afford it. now I might look for some 243 heads that are ported and bump the compression.
