Valve train refurbish + parts still available?

[typhoon320i]

I'm planning on doing my valve stem seals this fall, and I'm going to pull the head off to do it, (never pulled a head off before) and since I have it off, I want to replace any parts recommended since this engine has well over 200K on it. I welcome any comments or suggestions about Items I should replace. (Question: are this parts still going to be available? if so where? Is Ireland Engineering still functional? I can't get my calls or e-mails returned)

Items I'm think about replacing:

head bolts
head gasket
valve springs
timing chain
timing chain tensioner
valve stem seals
timing cover gasket
valve cover gasket
Clean carbon off the top of pistons
have a machine shop check my head for flatness.

My $0.02:

No need to replace the following:
Head Bolts: These are not stretch bolts, so they can be re-used if in good condition. Just clean them up.
Valve Springs: Unless you are planning a cam swap and want to run higher rpm, the springs are probably fine.

The rest of your list is good practice.

$450 for a rebuilt head, ready to bolt on? Sounds like a good deal to me. Looks like they are out of Dallas. Im definitely interested.

Yes, they prepay for shipping back the old cylinder head as well and provide a box for it.

I'm think about to do this soon.
Do you know.....I assume the head is decked, and they have done a valve job, tested the valve springs. new seals, valve guides...
Do you have any pictures of it before you installed it?
So you were happy with your end result?

[320iAman]

Yes they do what they list and deck the cylinder head and spray a heat coating on it as well-viton valve guide seals to boot, send them the upper timing chain cover as well as they deck this with cylinder head so they are even. They do a good job and cost less than local shops by far. The pictures are buried somewhere.

+1 on Randy’s recommendation CHI took care of a head rebuild for me and the turnaround was fast.
