http://www.summitracing.com/parts/cca-20-618-9 Comp Cam recommended for a 318. That's a good thing. The bad thing is the $320 price tag, add the lifters if you choose and valve springs and the budget is gone.
You can actually save some money not buying the lifters...factory style roller cams are very forgiving. The only reason you'd need to replace the lifters would be if they make noise...the hardened rollers don't have a wear pattern like flat tappet cams so you can reuse them without concern of wiping a lobe. I've done it at least a dozen times in Ford engines with absolutely zero ill effects on daily driven and dedicated street/strip use.
