Another thing you have to think of is if you use different cams you need to make sure the gaps and clearances are the same. I talked to my neighbor who was a toyota master mechanic and he told me that when you buy cams you will have to do alot of work grinding valves and changing the valve caps with shims and measuring with a feeler guage to make the it worth your while. He told me on a overhead cam its alot more difficult than the regular motor because you dont have the hydraulic lifters to make up for the imperfections in the valve length.
