After putting the cam and lifters in my 499 build, my engine builder noticed the holes for pushrod oiling come out the lifter bore slightly. This is with Comp 892 lifters. I know some of you guys have used these successfully in an unbushed block. Did your lifter bores also have enough chamfer that the oiling holes were exposed? I'm obviously concerned with oil pressure and I'm trying to explore my options since I'm not real keen on spending $800 to bush the bores. Is there a better lifter to use; maybe one where the oiling hole is just slightly lower on the lifter body? I'm all ears for what you guys have had success with. Thanks!
