I've been seeing a few people asking questions about cams. I decided to look elsewhere for an answer and I came up with this site. Helped me out a ton. http://www.newcovenant.com/speedcraf...camshaft/1.htm
It looks childish, but it helped me understand a lot. Also, a bunch of people say that our heads flow best at .500, and not to get a lift greater than that. There was something interesting about that on (I believe) page 6.
on average, our heads flow best up to .500 lift. some may flow better or worse above that depending on the casting. some good info to know is:
lift should be matched to head flow, add more lift if the heads can flow better w/ more lift.
duration should be matched to cylinder displacement. more displacement, more duration.
lobe separation should be used in conjunction w/ duration to achieve the desired powerband and overlap characteristics. more overlap means higher rpm powerband, less overlap means lower rpm powerband.
intake centerline should be adjusted acording to the type of powerband desired. more advancement for a more peaky powerband and more peak power, more retadration for broader powerband and less peak power, but higher average power.

Well the number one flaw with lifts higher than .500 is our heads only allow up to about .520 until you make contact w/ the valve seal. Thus flow is not our real limitation. The lame head design is.
