What cam should I get?

Man this sucks. Hughes racing says "Maximum lift with stock guide height is 0.450", more lift requires shortening the valve guides. " In that case my moms car has a higher lift than that and it is a toyota. I'm not sure if the guide height has been shortened on my motor but this is getting be a pain in the a$$. When I had my big block Charger all I did was ask a few questions, bought a Purpleshaft cam and BANG I had a radical idle and it hauled booty! And had no valve train problems at all for over 5 yrs.
