With that combo you should be making 375 rwhp which converts to 400 hp at the engine. You may clearance issues. You can do two things. You can get the piston notcher from Isky cams and do it yourself, go to a machine shop and there is new technology that allows them to notch your pistons while they are still in the car or you can use an air dremel with a diamond bit and do it yourself with a premad template that you could fashion.
If you dont want to worry about the clearance issues then you can go with the AFR 165cc heads. They will make better low end tq but will not really be enough if you choose to go to a stroker later on.
If you really want some much more thorough advice than what I can give you then call and talk to ed curtis at Flow Tech Induction. you can get their number at
www.fti.com. You tell him your situation and he will recommend your best route and the best combo for the type of performance and driveability that you are looking for. Dont just take my advice and buy all of these parts. Do a lot of research and then do some more. I have had great experience with my AFR 165/Crower 15511 Cam/Cobra intake. But I am EFI and even more limitin is that I am using a Speed Density computer system instead of the Mass Air Flow system that is more flexible. I also live in CA so I have smog to deal with.
I would really talk to Ed curtis. You will probably have to notch your pistons since you can go pretty big with your cam, bigger than efi motors, and that means less clearance.
If you have anymore questions feel free to ask. I know alot about the SBF setups through my 5.0 buildup. I did tones of research and almost bought those y-303 heads from Hawaii Racing but then I decided to just go all out and get the Infamous AFR heads. They are without a doubt the best street/strip heads on the market and are worth every penny.
Unless you absolutely cant spend the extra few hundred $ then go with some TW heads or some cheap Y303 aluminum ones.
