eddy heads and what rockers to use?

i am looking to get eddy's 340 head 60179 for my 1970 340, and i know that they say you need adjustable rocker arms. So i am wondering if the proform ones work or what works if those don't. eddy guys told me to buy the indy ones and there web site says like 1500 for them w/ shafts so i need a alternative please....
Thanks, Ryan
