do you need a special tool to get the valve guides out? and where is the best place to buy them? thnx guys

like valve seals? that wut your replacin? you can...

A) use an adapter for an aircompressor line to screw into sparkplug hole and compress cylinder

B) stuff a length of rope in to fill chamber to keep valves from fallin and change 'em

C) take head off, rent tool from crapozone, change seals and headgasket as preventative while your at it.

or just pay someone. bring it up, i'll have her done in a day or 2.

oh yeah! advance had valve seals for like $18 i think. maybe $12

hmm... not gonna say for sure as i've never done it. just talked to my buddy the other day about doin the head on my truck and he sed if i'd bring just the head (as i dont have the tools necessary) he'd rather fix 'just the head' than work with the head on the truck.

You should take the head to machine shop to replace the guides. The guides have to be pressed out and back in and they have to be honed for the proper clearance. Another option that might be cheaper is to have the shop install guide liners, That way you can still use the guides that are in there and don't have to remove them.

How many miles are on the head? If the head is apart already and you have a dial indicator you can check your self to see if the guides are worn out of spec. Pull the valve off the seat about a 1/4", Place the indicator on the side of the valve face, set it to 0 and rock the valve back and forth. The valve should only move about .005" - .006" any more than that and you need to fix the guides.

i think there is just over 100,000 on the head. i was just tryin to save some cash by having my friend install the guides and seals. how much do you think they would charge to put in the guides?
