how much cam with performer rpm heads?

WOW! Way to go digging up this old thread. (2010!)
It’ll probably help someone out.
I just happen across this article & curious how much peak lift stock Eddie RPM's would handle? I don't live on here. Didn't know how old post was. Added my 2 cents because rating is .575 , machinist said .530 at best. So much for ratings, what else is inaccurate? Not a Guru, just thought the inaccuracy was note worthy.
Sorry that my ignorance caused you
to want to exploit it.
