the head i got with my engine happened to have some 858c tighe cams in it (260 8.4mm i think lift) so I decided I would just use them.. the specs say around that much lift.. and i though, longer duration would really change the power curve more than increase the power?? ..

anyway, they are near new cams, and i was thinking around 272 is what i wanted to go before i found out they were aftermarket.. could even possibly sell them? They dont even have ANY wear marks on them yet..
