i have a 5hp briggs (flathead) that i'm hopeing to build up over winter, i don't want to make anything to crazy. i would like to get a rod, cam, valve train, and maybe do some head work. what would be a good all around cam, are there any that could stock valves? if not what valves, spings, keepers, and lifters will work with it? also what would be a good rod to use? thanks for any help.
