Im no expert on chevys or engines in general, but being a student im good at saving money... and that looks like quite a bargin. i was considering a full roller valve train (mostly for component life) but choked when i found the av. price. It was over 1100 just for the valvetrain (w/o valves). the cam looks like the sort im looking for... huge torque. if the heads are good, and the whole setup isnt badly worn (with rollers it shouldnt be!) i would go for it. im sure someone who knows theyre stuff will correct me though
