Comp Cams and Isky as well as other cam companies have detailed info on their websites for checking and determining the best rocker geometry. Just browse them, and make sure you get a checking pushrod to get the right pushrod length before you order the ones you plan on using. To explain all of this is very detailed and complex, but actually doing it is very easy and you will have no trouble following their guidance in doing it. Ideally, if you placed and centered a nickel on top of a quater, and the quarter represented the valve tip, the nickel would be the area you would want the rocker tip to stay in as it travels thru its start to finish motion. Making sure it doesn't stray to close to the edge of the quarter, or even off of it. Good luck, keep us posted.
