5.7 Vortec Lifter Replacement
My 2002 5.7 Vortec V* has a bad intake gasket that is leaking oil badly so I am looking at some time to replace it.
While I have the intake manifold out, I think I have pretty good access to the lifters which have developed a tick that I can't get rid of.
If I do replace the lifters while I am in there, should I replace with the Delco HL123 lifters or go with something aftermarket? Should I replace the push rods at the same time or just clean them out?
I have heard that small passage in the push rods can sometimes get plugged and that slows the flow of oil into the lifter which may lead to the ticking noise I am hearing. Is there a better way to clean these passage ways other than soaking the push rods in cleaner?
If I am going to go through the added trouble, I really want to eliminate the ticking noise!
Anything else I should clean, replace or adjust while the intake is off?

Soaking the push-rods in solvent or a "cleaner" like "Gunk" will not clean out the push-rod interior oil passages of excessive carbon build-up.
As far as new valve lifters go, you can spend as little as $120 dollars for a set to over $400 dollars, depending on which brand that you choose to go with.
If I were you, I'd yank the valve stem seals off and install new ones, considering the age and mileage of your vehicle. Might as well put a set of Iridium spark plugs in,
if you choose to change the valve stem seals.
