383 with Eddy heads!
not sure what to say. I have a set of 906 heads on my 10 sec street car. maybe I have 400 dollars into the heads. when you oversize the valves you get a nice fresh seat on the heads. Do you plan on tring to drive the thing 200,00 miles? then hardened seat is really not needed. 452 heads have a hardened seat but its only flame hardened. it is not a seat that is pressed into the head like an aluminum head would have. all my motor is, is a 400 block with 440 crank that uses small block chevy journal on the rods to offset gride the crank to 3.9 stroke. its 470 cubes and makes all its power under 6500 rpm. because of the heads. calulated out so far the HP is around 530 actual HP. the eddys would probally make more power but not much. I have a set of B1 heads with 2.400 intakes that flow almost 460 cfm on intake and 325 on exhaust. just waiting to buy a aftermarket block for that build. my point is that you can make good power with stock heads. and not have to spend a fortune. and one more thing. rollers cams do not make any more power because there is a roller on the lifter. it makes more power cause you can run higher lifts and more duration. and steeper ramp angles.
