I like my rods a little tighter than my mains. I try to go .002-.0022 on rods, and mains at .0024-.0026. As Mr. Weld said above, the solid lifters on a hydraulic core is a no no. I've successfully done it the other way, with hydraulic lifters on a solid core, but the opposite usually doesn't work long.
What weight oil are you running? Are you running roller cam bearings?
