My Roush was sucking
oil down the valve guides at 13,000 miles. We did a leak down test and found a couple of cylinders were at 35% leak down. When we took off the heads to do the guides and seals, we found a couple of cylinder bores were scratched and the rest looked like they had 100,000 miles of wear. So, we pulled it apart and found two pistons with small cracks. That's why the full rebuild.
If your
oil use isn't excessive, do a leak down and see what you find. If all is ok, just replace the lifters and leave the rest alone.
