SCORP! question for ya?
Scorp,
am i remembering correctly that you had some valve guide work done? or am i in left field. i wanna say i had followed a thread of yours where someone was recommending you get new ones instead of reusing your old ones, i could be completely wrong on this matter but i figured i would ask. let me know if this is on target and if so i have some questions for you.
thanks man,

Re: SCORP! question for ya? (scorp508)
Scorp,
To change the valve guide, do you have to take the head off?
I ordered the valve stems from Summit racing, asked about the valve guide the sale person told me that to change the guide I need to take the head off :eek: So I just get the stems. Should I get the guide also? If it involve taking the head off, I'll just send it to the shop to do the whole head :crazy:

Re: SCORP! question for ya? (lcvette)
You have to take the head off to change the guides, because you have to take the valves out, then you have to knock out the old ones and knock in the new ones.
It is best to take it to a machine shope because they have the right tools to do it, but but make sure that you nead it befor you do so maybe the guides are just fine.
Hope this helps

Yes, the heads absolutely have to come off. You're better off sending it to a machine shop to do. I was/am kind of lucky in my position as my grandfather was an automotive machinist, and passed down a lot of knowledge to my dad, who taught me a bunch doing this project. We have valve seat cutters, heavy duty presses, and other tools the normal everyday home mechanic doesn't have which are required.
Anyways you have to (quick and dirty list).....
:::Remove everything from the head.
:::Press out old valve guides
:::Press in new valve guides
:::Hone new guides to correct inner diameter
:::Cut top of guides for valve seals etc..
:::Regrind valve seats
:::Reinstall all head parts
...there is lots of minute measurement and calculations going on during the entire process. If I didn't want to learn how to do it myself, I would of definitely sent them off to a shop.

:eek:No thank you, I will not take the head off now. I'll will try the water pump, timing chain, intake gasket, steering rack in the next two weeks, plus the fuel pump this weekend. Don't know when I'll try the stems even though it arrived already.
I am way over my head on this tasks, hopefully my brother kept his words and show up to do the timing chain for me

Re: (VQT88Vette)
ok, so, in my case the valve guides seem to be fine, but i am changine springs and am suppose to use the spring shims that came in the kit, it says i need to, so if i have mine pressed out can i reuse them and have them pressed back in? and if not about what kind of dollars are we talking for a set of valveguides on an LT1?

I think reusing valve guides after pressing them out would be bad, but I don't know for sure.
