I want to take a 305 block and put 350 heads on it, I know I need to mill the heads to get good compression, I plan to use heads with 64cc combustion chamber and 2.02 intake valves, cam with 218 duration and .440 of lift fed by a rochester quadrajet the idea is to get a good compression good flowing engine that doesn't use lots of gas on a very low budget but I have no idea if this will work like I want, can anyone help?
