whatever cam you buy....buy the supporting springs to go with. that .02 cents up above is just like 2 cents in todays economy...worthless.

with my B cam which is barely more lift than stock had valve float. match your springs to your cam or risk damage. nuff said!

Is it ok to have a spring with a max lift of .542 and use a cam that only lifts .510?

I know that the cam shouldn't lift the valves past the rating of the springs, but is vice versa ok? Just wondering if the above items I posted are a match....
