What springs come on eddy performer RPM heads

I was quoting Brookshire who said he used the same formula for the Chevy and Dodge voodoos posted above
From what I understood they were evolved from the Comp xt lobes
I do not know that he did any .904 hyd lobes while running Ultradyne
and IDK if Howard's endended up with any hyd profiles out of the several hundred of the latest they aquired
one thing to take away from that previous post is that you have to be very very carefull buying from E-Bay (or anywhere really) we each have to be responsible to get what we think we are getting
