Switch to solid lifters with oem cam?

$2500 just in MACHINE WORK!? don't seem right/
I once bought an 87 Dodge Van with a 318, and it rattled as I brought it home. The exhaust on #7 lost its clip and the pushrod wound up wedged into the lifter body with the pushrod cup flipped up beside it. I replaced both pushrods and lifters on #7 and drove it a good 50K trouble free miles after that, til it got wrecked.
