Your soil sounds good, but if you want to make the clay bit easier to work then add compost. Manure is good too for improving soil texture, most plants deal with it when it is well rotted, dark brown and crumbly. What are you planning that doesn't like it? Grow More is a fertiliser, usually plants that don't like manure don't like fertiliser either, shrubby Mediterranean type plants that like poor soil.
