z400 rebuild head question

[ceofuller]

I ordered up some kibblewhite titanium springs, seats, retainers and washers. I also have some kibblewhite black diamond intake and exhaust stems and DID chain.

Question is, do I have to have the old valve seats pressed out and the new seats pressed in? Or is that something the basic do it yourselfer can put in while in the garage?

Thanks, and any other tips you may have for making this easier is greatly appreciated.

you should have the valve seats ground ,yes they are very hard some of the hardest ones out there . so like wise you need a valve to match .
i have a phone number of some one that can do that for you ,he's on m15 PM me if you want the number

If you are talking about Tim on M-15 just north of Davison and Clio that is were I take my stuff and he will get the business on this too. He is one excellent dyno dude. I have him on speed dial on my cell. ;)
