moper. how do you remove valve springs from an assemble motor without
an air source?
As for tech lines, I would not take everything they tell you as gospel. I've
gotten bad info from tech lines several times. Comp's tech line recommended
a set of pushrods for my comp roller cam and springs . After I bent several of
them (I attributed it to over revving) I called and again asked for there advice for a set that would work for their cam and springs I was using.
They sent me the same set again, only this time I called the tech line again
before installing them to confirm that they were in fact right for the application. This time the tech informed me that they were no more than stock replacements!!! And in fact they had no premade pushrods that would come anywhere close to that application!!! Then they told me I could return
them , but I had to pay shipping.
