I am currently running yella terra roller rockers that are 1.65 ratio on my ecotec V6, from what I have been told .080 pushrods and 135lb valve springs and a valve spring has just snapped in three places. Is there any suggestions as to what I can do after

To help resolve your problem, we need to find out why your valve springs are breaking in the first place. In order to determine this, we have a couple of questions which we would need help with answering. Are you running a larger cam then factory? if so what are the specs? Also what type of retainers are you running? The reason for this question is because your current retainer may be providing you with an incorrect spring installed height. How may kilometers have you traveled since installing these valve springs? Have you contacted the valve spring manufacturer?
