Economical replacement rocker arm set?

Hell yes use them. I found those things hanging on a shop wall where I went to work in 2003. Just so happens that my cousin needed them. So my cousin bought them, I ran a pin hone through the bore because someone didn't banana groove the shafts they were on, and most likely thought 10 psi of oil pressure was enough and bitched up the bore. I also touched the pads on a valve grinder and on they went.

IDK how many miles he put on them, but I'd bet between the two of us there is more than 100 mid 12 second passes on them. I'm sure he probably put 6-8k street miles on them. Then he dies in 09 and I bought the car in 13 and put another 6500k miles on them before I took the engine apart October 1 2014.

So yes, use them. If I was going to drive on the street I set them at 1/2 turn of preload and when we were going to the track I set them at ZERO and beat the hell out of.

I was almost always .1-.15 faster than my cousin. He got better at the end but decided to do go cart racing for awhile.
