Stock heads and flow #'s
What are the stock heads flow numbers? Intake? and Exhaust? I just read some aftermarket heads flow 250 Intake and 180 exhaust. And I wanted to compare those #'s to stock ones. Thanks

The book says that stock 186, 350 castings flow :
0.250 - I 125.3, E 89.9
0.400 - 177.9, E 118.7
0.500 - 178.8, E 122.2
Not so good in my opinion, however, these heads respond very well to exhaust port modification.
Hope this helps.
