Budget tune 318 la

FYI this is what an LA "roller" or Magnum valley looks like with OEM valve gear

There are 8 "dog bones" the figure 8 shaped pieces that fit over the tops of a pair of lifters and keep them aligned. The block is machined to allow them to fit. Over the top of this is the spring sheet metal spider which holds them in place. The bolts are tapped into the bottom of the valley, so THAT is a difference

None of the earlier "non roller" blocks have these features
