My cam is as described above(not as you describe). It is not the "off the shelf" product. Not sure what the advertised duration is(info at the house), but the duration at 050 is 221/230, and lift is .454/.454.
The heads flow 260 cfm +, especially considering the additional porting to be done...and are considered the "fast burn" combustion chambers.
I think reality is somwhere between our results...and it all looks good to me.
Thanks again for your interest.
