Best Stock BB Heads?
A stock 346 head usually flows 215-220 intake and mid-150’s exhaust @.500 lift, and the typical 906 can range from high-220’s to low-230’s, with the ex basically the same as the other heads....... in that mid-150 range.
The “really good” F heads can be in the mid/hi-230’s stock.
This is what a nice bowl job on a 346 looks like:
