My application is 4x4 offroad use in a chevy truck with 40'' tires, Im looking for big H/P within 2000-5000 RPM. My question is with heads, and what brand. 118cc. chambers give me 10.1 compresion and 124 chambers will be 9.4. I want a gut shot between the two and want aluminum. however the intake runner size has me confused I'm thinking 300-325? With a dual plane intake?

Any thoughts?
