Cylinder head removal and valve question

did you use any grease?

I used a ton of grease, probably too much. I ended up not being able to get out the aluminum chips that went into the combustion chamber because of the grease that clumped it into the corners.

If you need KZ intake valves I have a box full. Pay shipping and I'll send you 4

what kind of tap did you use? the grease should catch all the shavings. supposedly it is better with the piston at tdc so the chips have less distance to go if there are any. that and the obvious at this point is the valves.

Hes already got some coming

It might not be a bad idea, it may not work due to the design of the cylinder head. There is a technique for some heads to take a drill on the end of the valve with the valve covered in grease and spin it while it is in there to wear the seat so it seals better.

Thank you for the offer

I used something called 'sav-a-thread' you find at autozone. Woulda worked had I not hit the intake valve and cleaned up a bit better

Are you talking about lapping the valve?

it is decidedly so.

Ya I plan on doing that when I get the valve so it will seat better.

On another note, I've been researching and I'm hoping someone can chime in but I've read that I have to get the valve and valve seat machined to fit?? Seriously hoping not

Would install the replacement valve, and determine whether it's properly sealing in its seat while the head is still on the workbench.

If not properly sealing on the workbench, it won't properly seal after reinstalling the head.

Don't go overboard with the lapping, as lapping isn't a substitute for grinding the valve and cutting the seat. Excessive lapping can be detrimental to the ideal fit desired between valve and seat.

With modern valve grinding and seat cutting equipment, lapping may not be required at all.

The FSM will explain how to achieve the desired valve/valve seat contact area (i.e., neither too wide nor too narrow).

Good Fortune!

Whatever you do...DO NOT use a drill to lap the valves. I saw some knuckle head video on Youtube where a guy was doing that. He used more lapping compound on a single valve than I use in a year

Ultimately, in everything you do...ask yourself one important question. Is the effort and cost going to justify the end result? Which brings to mind the next point to consider...

okay. I think I can lap it properly but I could bring it to a machinist and have them cut a new seat right? What are my chances of doing this by myself successfully? How do I go about finding someone who can do that? I googled a little bit but didn't find any leads.
