My Trends have the .014 oil hole in the cup to restrict the oil flow....works great.

I did have to shim the cup to eliminate all movement. The reduced oil hole diameter allowed too much oil to stay in the lifter, raising the cup and holding the valves open as RPM increased.

This has as more do with the block (raised lifter bores) and lifter clearance (.0015) than the lifters. I know several others that used the .014 cups with no issues in stock blocks and/or those with a bit looser lifter clearance.-Al
