Are the earlier pre-edelbrock aluminum hemi heads similar or a lot lower?

pre edelbrock heads, mine were terrible:
.100 82 82
.200 147 145
.300 213 195
.400 245 205
.500 276 205
.600 287 205
.700 290 205
.800 290 205
after a mild port job
.100 82 82
.200 159 158
.300 235 225
.400 284 229
.500 317 232
.600 329 234
.700 337 236
.800 344 237
these could obviously go a lot more, one day when i get a chance. but it was a noticeable improvement.
