How to identify "302" heads???

Ma mopar got it right for Emissions but the 68 and later 340 cam is a smog cam masqueradig as a performance cam
closing exhaust late to give an egr effect with exhaust dilluting the intake charge- who needs that
you have to unnecessairly rev it up to clean up the charge
opening the exhaust early- see aj's posts in Jeffery's thread concurrent with this one - expansion ratio
and advancing it makes worse on the efficiency side
Hughes stroker cam recommendation
closing the intake late even late for a stock real 9.5:1 340 and really really late for a 360 or late 318
DCR goes all to hell
who needs the really long ramps especially the uper long closing ramps
good points KISS
now if you blueprint to a true 10.+ CR and run low gears I've raced it there when we had to iven with the crap 68> heads
