I want to get my 823's ported but where? I am building a 408 gen 3 block and my goal is to get it spinning about 7500 rpm. I have all good internals to support that rpm range. I have stock 823's with ss valves and good springs for them. The car is being built for autocross and therapy (Keeping the voices at bay). I see a bunch of porters online and not sure which one will fit my needs. I am ready to pull the trigger on getting done. I guess I am looking for someone that has run these ported heads with real data to help support my decision on where to source my work to be done. I am not looking for just wot results but thats important too. Mid range is as important as well. My intake choices are something like vic jr efi manifold. I like to hear from ls head/motor builders and help me spend my money.
thanks for reading.

There are many options to choose from, the others mentioned are good. I had Land Speed Development port my LS3 heads. Brett has several different LS3 port options that he offers and can customize for your combination. Great guy to deal with and I've heard nothing but good things. I don't have results yet though, still working on my build.
