AFAIK, it is indeed stock. Could the backfire be due to too much air being
pumped into the exhaust manifold while there is unburned fuel to explode
there? WOuld a bad "gulp" valve be the source of my former problem? At any
rate, now that I can lawfully get rid of the smog crap (Cali exempted my
'70 this year for ever YIPPEEE!), I will pack it up in a box and store it
someplace in the garage. 

BTW, our fix was the same as yours - pull it all off!
