Looks like I cant change the mistake on my Post title sorry for the typo - special roller rockers... Ok. I am in the middle of gathering some pieces and parts I know I wanted. I was able to score a set of eddy heads for a 340 stroker build I am hoping to do (no real racing, MAYBE some autocross mostly cruising), yes I know overkill. I would like to have roller rockers and was dreaming / drooling over a set of Harland Sharp rockers but then I saw they have a "Special Set" just for Edelbrock Heads. Without calling anyone, or talking to any vendors, I wondered if the A-bodies Forum crew might shed some unbiased light on what the heck are they talking about... Thanks in advance for any insight.
