My engine guy had enough problems with Comp cam solids that he was only installing rollers. His business is 99% race cars but has put some small rollers in a couple Z28s. I am pretty sure the one was a Howards that a lady is now driving the car after her husband passed. I drove it a couple times and had good vacuum and really responsive. I believe this is the part number 111213-10.
If you run a solid, use the lifters with the direct lube hole in them. Friend of mine seems to get along good with those.
I just built a 427 small block and used a crower 00425. They said it should still have enough vacuum to run power brakes. I had a 140 cam in my one Z and it was not the best for power brakes!
With a roller the lifters get expensive, we get billets, and you need a cam button.
