Hughes 5003 lifters

I think hughes calls for .080 to .095 preload on their lifters. Your at about .042. If 3/8 fine thread.

Yes, these lifters require more preload. I 'm using stock non-adjustable rockers in my 340 and had to measure and order longer pushrods to use the 5003's to get the correct preload.
