Edelbrock performer heads on a 305?
Would Edelbrock performer street heads part number EDL-60859 at summint racing. The heads say that they have 60 cc combustion chambers i think. Would that change my compression ratio? I dont know much about heads but I know i need some for my 305. If anyone could help me out other than saying I should buy a 350, it would help a lot. Thanks

Stock 305 heads are 58 cc, so a 2 cc increase won't amount to even a half point loss in compression. The heads will deliver at least 30 additional horsepower--sounds like an excellent choice to me 
PS Make sure the intake valves are no larger than 1.94 inches so they fit inside the cylinders.

The valves are large so you'll be limited to cams with less than .450" lift at the valve.
