Stop in for a cup of coffee

I would go with #3 and a set of Rhoades lifters... It's the only one slightly bigger than the stock 340 cam...
I wouldn't know how to test for comparison purposes but how good are the Rhoads lifters? Are they precise enough that all the cylinders work the same? And because Chris is talking about a Poly, are the cams he mentioned hydraulic or solids. Poly's were all solids.
