Crane Roller Lifters OH NO!
^^ Ya' know..$300 for the cam and $300+ for the roller lifters to get you how much more power? People don't like roller bearings in their roller rockers but they would run roller lifters? K.I.S.S: It is the street, how fast can you go on it and not kill anyone? Race motors are the exception. Lots of benefits from a solid roller.
