I sure wish I had a set of these back in the 1970-1980’s. I kicked a lot of azz street racing with junk parts. I can’t imagine what I could have done with a set of these.

I bought a set a couple years ago. They are setting in the basement. I should get busy with my roller cam 318 block. I have a decent machine shop nearby that also has a dyno. It could be a fun project. I need to look up your flow numbers and see how low lift looks. It's only a teen, no reason to go crazy!
