The original poster has a 6A which I also have and with a 76 inch prop, I think I have about 7.5 inches of ground clearance with nobody aboard and have had no issues with picking up rocks. That being said, my airplane has never seen grass strips. The 7A has a much more level ground stance and it seems as though the main gear is longer to me which might give you a bit less prop clearance than on the 6A.

Don't think a 74 inch is anything to worry about on a 6A.

Can any one see any problems with this combonation? Would I be better off reducing the prop by 2 inches? Any advice would be appreciated. Cheers.

I know of one RV-6 that had a 74 inch prop. The builder sold it after flying around 200 hours with no problems. The new owner was doing transition training (with an RV pilot / CFI) in it and hit the prop on a wheel landing during the first two hours.
