what the max. lift for stock 5.3 valve springs? i just purchased a tr224 .563 114" i was wondering if stock valve springs will work? if not how hard is it to install springs and is there any measurements that need to be checked? thanks for all the help
Comp 918's will work.
Did you even read? He asked about stock springs.Quote:

Chill dude,
When i say 918's, I meant that the stock springs cant handle a tr224. That's all i thought was needed to be said.
Stock springs are a no go, valve springs aren't hard at all just a pain in the ass and time consuming. Comp's 918's are a popular replacement as are the Patriot duals. I'd go with duals if you wanted to spin the motor higher than 6000
think max lift is like .500,,,i ran a 522.529' on my stock springs on my 5.3.
i wouldnt risk it thought with that cam
at the very least, do LS6 springs.
