| + | *In this build, I would be interested in spending the least amount of money as suggested by the OP. In that vein, I would use stock *rail rockers. Lift is under a half inch, so I would think the rr would be ok. Since I'm not sure that all locks locate the valve tip *the same, relative to the top of the retainer, I would welcome input from others about using a (-0.050") lock (that's what's listed *above.) to insure the valve tip sticks up far enough above the retainer so that the retainer top surface doesn't get loaded by the *side rails of the rail rockers. | ||
