I need help, is it okay to use the original springs or do I need to upgrade? Dutra RV10 cam. Links would be helpful if I need to buy new. Engine is at the machine shop now, had to go.020 over.

Stock springs will work fine. I cannot say whether your old/used springs are any good or not. They are not expensive and likely your shop can order them.

Thanks Lou. After thinking about it, figured it's best just to pony up and buy new. Bought the comp cams 901/944 springs/retainer as recommended in other threads. Both were tough to find, especially the springs.
