help choosing an afr head
i was going to get tony mamo to port my 195cc street heads but he thinks its a better idea to just buy a new head. im trying to decide on 3 different heads. 195cc competition, 210cc race, 210cc competition. it will be going on a daily driven 396 with some nitrous use. id like to hear from afr themselves but any useful knowledge is good. i will have a custom gind made for this motor and im gonna need someone to port the intake to match. im also curious why the flow numbers on the 210 race are less than the 195 comps.

You have a 396 and he wants you to use 195's? I have a 357 and I am running LE2's which are 205's. Give that thing some heads that will really open it up! Lloyd Elliot Heads OR Advanced Induction Heads! Leave AFR out of this lol

If your going to quote me at least do it properly.....
This is the latest I PM'ed you a couple of hours ago....and I still stand behind what I typed. Sounds like you want the bigger head but thats not the right choice for everyone. It depends on your application, driving style, and how much you value extremely responsive crisp part throttle operation. You always trade some of that for the larger race heads that move more air. For someone that is lucky to get to the track once a year its a bad trade IMO...for a guy the street races alot and see a decent amount of track time its a good trade.
And the 210 Comps flow more than the 195 Comps.....you should either get the 195 Comp's or the 210 Comp's.....the 210 street will save you some money but the 195 Comp's flow the same with a smaller runner for better low/midrange grunt.
Dont get me started on the comparison of ported stockers.....they need 230-240 cc's to flow close to the 195 Comp (an honest 300 CFM head) and the 210 Comp will blow them away with a much smaller port. The velocity and overall flow curve of the AFR clean sheet design is much stronger.....then add the quality of the new castings, .750 deck thickness, lightweight 8mm valves and spring/retainer hardware. There is NO comparison
Thanks,
Tony

Either head would work well....just a matter of where you want to hang your hat

The old 210 race head (like mine) was pretty crappy. They were about 200cc TOPS and the flow numbers from AFR were pretty "friendly." We had to take ALOT of material out and throw a good 5 angle VJ to get the numbers we wanted, and they are definitely not a 210cc port anymore. The new 210 eliminator head though is pretty damn good. There was a guy with a 396 on here a few months ago... out of the box afr 210 eliminators, big HR cam and he laid down ~470rwhp. For a 1500 dollar set of heads that's getting it done IMO. Local guy had the competition 210s, he spent a few hours taking some of the pinch out and working the ssr... 383 made 720 hp. Granted it had 14+ compression, and a large by huge solid roller, but it shows the potential of the casting. Kinda makes you wonder why the Ai cnc work is so expensive, when AFR is giving you a completely new head casting AND cnc portwork on the eliminator head now...
FWIW I'm definitely NOT an afr nuthugger. The only thing afr about my heads is the stamping on the front. But I am impressed with the new eliminator line. If I could get decent money for my AFRs a set of air wolf 220s would be my choice

A 195cc AFR eliminator will flow more air, maintain a higher velocity, and make more power then a 200-205cc ported stocker.
Porting an inefficient head just makes it a bigger inefficient head. You need a totally different casting designed from the ground up with performance in mind, not just developed primarily based on its cost and mass production.

sorry tony. guess i should have been more clear. i do alot of street racing and its been seeing a decent amount if track time. once its all dialed in, it wont see much more track use.
having said that, im leaning very heavily toward the 210cc competiton.
what my plan for a cam is: buy a head to support the size of the motor that will still be small enough to have the torque for daily use, then call comp cams or who ever would be better to custom grind me a cam to match the heads. then i have to find someone to match the intake to the heads. this will never be anything but a hr motor btw
