+ | *Makes 9.6:1 static compression ratio. Cut block decks to zero and use a 0.040" head gasket. | ||
+ | *Use XE274H Comp cam installed at zero with Comp 981 valve springs/ 750-16 retainers/ 630-16 keepers and stock 1.5 rail rockers.... *1.250" springs should be OK because the cam is a moderate grind, hydraulic flat tappet.....Narrow the O.D. of the guides to less than *the I.D. of the damper spring and cut for PC-type positive seals...Cut top of guide for 0.550" play from bottom of retainer to top of *guide seal. Pin the pressed-in rocker studs with this kit.... | ||

+ | *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. | ||
