Making power out of the 318

Are 302 heads a true decent budget cylinder head for a 318? I'm between buying a set of 302's or a set of speedmaster cylinder heads.
to make any power thay need porting, alot!!!! and thay need bigger valves as well! thay good head for a mild 318 build driver or a truck... buy time you port and add big valves you can buy the speedmasters...
