[351C]

Well i need some advice. I have a truck 1/2 ton and i want to create some good low end torque on my 351C. It has a 650 double pump carb, 4v edelbrock intake and at the moment 4v open chamber heads. i need some heads that are closed chamber and at a good price should i got for the aussie heads?
i dont know alot about this sstuff im a beginner willing to learn so any advice would be great. Remember it's going in a truck so i need low end torque not street car preformance. I also have an RV cam in the motor.

Any Cleveland head will fit on any cleveland motor-351c, 351m, 400c, 4v or 2v. The carb size is perfect for that displacement. You didn't say what kind of intake it is, but you will need a dual plane for low end not a single plane. The 4v heads are only good for high end rpms and aren't great for street use in general since they lack the ability to make power at lower rpms. The 2v heads are perfect for low end power. Having said that the 4v heads are worth a lot more $ than 2v are. As far as 57cc or 64cc goes it depends on how much compression you want to achieve and how much your engine can take. I'd say go for the 57cc if your engine is already built with forged pistons and has a recent rebuild, but the 64cc are fine too and might be better for you since they are more streetable and less risky.
