AFR vs. ETP
I'm planning a H/C change this spring. My car is a grocery getter and my wife drives it. I'm going with a baby cam and am interested to know the concensus on who (AFR or ETP) would have the best set up for high torque and drivability. It seems to me that AFR's small port / high velocity concept is the way to go.
Would appreciate any feedback on this.

We have 215's and 225's on the way. Synergy, as do others, have some 255's on order.
The 265's that flow 402 at .600 are a race only head.
11 Angle (Race angle)
.800 Beafy Deck
Steel threaded inserts
B&B press fit hardened washers.
There is more clearance with less angle for a bigger cam without flycutting
Space for 3/8 pushrod
Correct Geometry

I really wish there were some side to side tests with these heads....
225 is too small

Kumar75150,
They are hugely customized deal and do come with a verity of chambers and sizes. I would talk to Rick. The heads allow a shop to truly customize to a particular build.
Also the price point for full complete setup for the performance is very attractive. Price is also based on components. EG. Jesels, will add a quite a few bucks to the final equation if you get them.
I do see your point on this and it is very good question. In so far as delivery, I and no else can run ET Performances business, Quality Assurance, Foundry, Machine shop, Shipping, Customer Service or control Demand besides ET Performance.
Time will tell.
I will however guarantee if http://www.synergymotorsports.net/ 1-510-796-3749 takes your funds for a set of ET Performance heads and cannot delivery them in reasonable amount of time, either Rick or I personally will take them off your hands and have your funds returned to you.
Regards,
Brent
P.S. Synergy also has a constant number of good size crazy builds going on for the foreseeable future. So it's really no big swing.

The funny thing is that you are completely right. These cars are accelerating almost as fast as the R&D.
