Think about this:
Those 1.85 rockers will give you a real boost in lift but not duration. In lies the problem. Don't expect much more than 8-10 HP maybe. Now add the cost of the rockers, the springs, and the labor cost to do the spring change; you might want to think about the HP to cost ratio.
The intake , headers,plus some tunning will give you the real power you're looking for. Just food for thought.

yes will be getting entire package springs and pushrods - and yes worried about cost to gain ratio!
