changing valves to different head

[MikeM]

changing this head of mine

is it simply a matter of cleaning up faces for the new gaskets ?

also valves after lapping in do the valves have to go back into same place from old head

[hairygit]

Valves need to go in whichever hole they were lapped to. If moving valves from one head to another, they will need lapping to the new head

[Paull]

And just to add when the valves are lapped in fill the crowns with petrol to see if they leak.

If not job done.

Hi,
     electric drill is quicker!

[MikeM]

because its my first time going to use something that easy going, seen the drill video on youtube but don't fancy myself with that

[Trigger]

Electric drill? Bloody cowboys 

[MikeM]

from what I can tell once you get a smooth ring on both faces your good to go ?

 also does the part the valve slides into  need to come out ? original head has new stem seals

valve guides ?

Speaking of that I've found my original Honda CB500/4 valve guide reamer. Not seen it for ages and it was hiding in my Snap On box. As I doubt very much whether I'll ever use this again I may donate it to someone on the understanding they will lend it to whoever needs it.

   Oddjob,

 it might be an idea to have a separate thread, "Special tools for loan"

the user pays postage ,and returns after use

perfect for smaller items

Hi,
     The electric drill reference was being sarcastic, although I have known one to be used. Slow and steady and not too much pressure, lifting the valve off its seat for a 1/2 turn now and then during grinding is the only way!

Oddjob, i would take over the reamer if you wanted, i have several heads if i can ever afford the guides!!

[Trigger]

Bryan, it is easier to put K-liners in.

[Bryanj]

K liners cost a lot to do mate, oddjob i will send you my address, no rush mate i still have to sort out all my special tools!!, i do have a copy of the common tools list if you would like a scan when i aint rushing back and forth to hospital for the boy!

[Trigger]

Bryan, the last box of 100 K-liners i got from the states was £40.

[mickwinf]

what the f is a k liner?

[Trigger]

Mick, in my spare time i do engines for the drag racing boys and we use them because the NOS gas and high temperature  makes the standard valves stick in the valve guides.
A K-Liner is a Bronze bullet valve guide. So if your valve guides are worn you can re-cut and put a bronze bush in.
