I have a 2002 Trans Am WS6. It is a 6-speed with Kooks long tube headers, off road y-pipe, Borla Exhaust, SLP Lid, K&N Filter, LS6 intake, Comp Cam .644I .598E 231/234 @ 0.050, Comp Magnum 5/16 x 7.400 pushrods, LS2 Double Roller Timing Set, PRC Gold Spring Kit w/titanium retainers, Powerbond 25% UD Pulley, MSD Spark Plug Wires, NGK TR55 Plugs and a HP Dyno Tune by G-Force Motorsports. Not sure if anything else was done to the car before I bought it but G-Force said the throttle body was ported. Not sure what gear it has but I think it is a 3.73. What are the best heads I can buy for this set up? I have 410hp to rear wheels now but want 500hp. I also will buy a 102mm Fast Intake and might also get a big mouth throttle body if necessary. Any suggestions will help me a lot.

trick flow/AFR are higher end heads....patriot are lower end heads. Do a search on Patriots, not many people like them and the Trick flows/AFR's are more proven imho

Supercharger will be last step after i get the heads but that is a lot of money. I am doing this project in steps. I still want to know the difference between AFR215 heads and AFR210 or AFR230?

casting (which has it's limitations) AFR's are hands down the best aftermarket
casting utilizing the factory 15 degree valve angle, TrickFlows are 13 deg.
castings and MAST @ 11 deg....rolling over the valve angle makes for a small
combustion chamber(raises comp.) yet still unshrouding the valves. Also the
port floor approach to seat on these castings improves midlift flow numbers
while keeping the runner small in size (cc vol.) This improves port speed
keeping the air/fuel mix atomized which helps torque (twisting force)......
YOU pay for the power !!!

The Trick Flow & AFR 215's are great heads. But don't forget the PRC 215's. They are way under rated. I love the set I'm running on my Z06. I paid $2,299 for the set, they have .650" springs, & come milled to your spec's at no additional charge. Also, the power gains are right with the other two 215 sets.
The main difference between the AFR 210, 215, & 230 heads is the intake runner size. The larger the runner, the more torque you will sacrifice on the low end of the power curve. Most people feel that 230cc is too large for a stock cube engine unless it has a power adder. In most cases, the smaller port with the higher velocity will make more power than a larger port that flows a little more air. Just look up some of the sick power numbers that the old AFR 205 heads were producing.
The best person to ask about heads is Tony Mamo at AFR. He is a genius when it comes to these topics.

The real "mid-price" option in this group is the Trick Flow 220 As Cast, which are roughly $700 cheaper with competitive performance.

You can make 243 heads perform just as good or better than any trick flow or afr if you are willing to spend the money.... Kaltech has done it and so has cartek. There is nothing wrong with gm heads. It's who does the work and how much money you spend that dictates the result. And afr's are a glorified 243 head anyway.

So many opinions..WOW! I would suggest calling a few and knowing your budget limitations as well but understanding what it will take to reach your goals. Be sure to talk to a few different manuf. yourself and not just one.
