Are there any flow numbers for stock port aluminum mopar hemi heads? I haven't had any luck in locating them.

these are from the edelbrock casting,, out of the box


intake
.1- 81.8
.2- 159.4
.3- 240.2
.4- 306.2
.5- 320.9
.6- 331.7
.7- 338.8
.8- 343.3

exh
.1- 68.7
.2- 135.9
.3- 188.8
.4- 209.3
.5- 198.4
.6- 199.0
.7- 199.0

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

pre edelbrock heads are lower,,,,

i usually dont flow stock heads,,, ill have a set of hemi heads to do for a stock thing,,, just had a valve job,, though i did some stocker nhra stuff but they were the m casting

These did have some minor bowl work, but no porting.

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.
