Reply to "Cam Bearing oil restrictors"

IMO the cam bearing restrictors are like a tiny splinter in the pinky finger while the lifter bores are more like a nearly amputated limb

the downward pressure of the valve springs onto the camshaft is already doing a fine job of shutting off oil to the cam bearings. if you just can't live w/o restricting the cam bearings, you can drill a new orifice hole opposite the manufacturer's & install them to use your oil hole instead and use the kit to do the #1 cam bearing in 4 engines because the front bearing has a lot going on behind it & must be set in proper orientation. the front bearing can & should however, be clocked to limit the exposure of the small orifice in the bearing face... & must not be set back more than .005"
