What is wrong with this picture?

Interesting!
My first Mopar had a 361 motor in it. I did everything to it that most people did to their 383s in those days (484 purple cam, Edelbrock DP4B intake, Carter AVS from a 440, windage tray, headers, open element air filter, Accel dual point distributor) and it really woke up. My Mopar buddies told me about the potential valve clearance issues if I went to the 915 or 906 heads and tried to run big valves.
I ended up rebuilding the original heads with the same size valves.
