Unused Rebuilt Head

[texasz]

I will soon be getting a head that was rebuilt a couple years ago and has never been used or installed on a block. Are there any special considerations that I should be aware of before trying to bolt it on and use it?

I'd bolt it on, then pour a quart of fresh oil over the cam and valves to lube the cam and let it soak into the valve seals for a day, then fire it up.

You could also let it soak with a light coat of oil for a couple days before you install it just to soften up the valve seals.

That's the kind of aswer I wanted to hear. And pretty much what I expected but had to make sure.

I may have to build on this thread after I get the head.

TexasZ,

Before you install the head, you may want to lay a straight edge across the head just to make sure it is flat and true. Check it from end to end as well as across. Also, if it looks like its been milled down (resurfaced) check that it has not been milled too far. I've read that too much milling can cause problems with the cam tower height. There's a post some where on this!!? I don't know the details on it however. Just something to consider.

I'm completely new to the internal workings of an engine. How would I know if it has been milled down too far?
