Head flow question

There are multiple threads/posts with stock flow values, there are differences between "169" & "447" castings particularly if bone stock & untouched with like valves. There's one "169" casting, "James Jagger's" '68 head, 140/[email protected],146/[email protected],147/[email protected]. Pretty typical for a stk head with basic, quality valve job. A quick bowl blend/cleanup can pick up [email protected], & [email protected], no real change .300& down. My bench wasn't as "friendly" to the stock "169" when I checked Mine, but I prefer a stingey one anyways.
