If what your saying about the pushrods is true then answer this for. All LS engines after 2007 that are not a DOD lifter are a ls7 lifter. So with that said when you look in the GM catalog if you look at a 2001 LS or a 2009 LS3 or a 2010 5.3l the pushrod part number never changes (10238852) from a stock 7.400 length.....The pushrod length is not only based on lifter but also based on the base circle size of the cam, deck height of head, and deck height of the block........
op... you better clarify your push rod length with an engine builder and clarify about that seal. Playing guessing games to save a buck or two is gonna be costly in the long run

Ok so i guess pat g and geoff at eps are the dumb ones for specs that require a 7.425" push rod on every gen 4 motor ive ever put a cam in or done a DOD delete on
