Default Re: Cylinder head questions.

The most sensible recommendations I've seen are that the coarse threads on the studs should get a light coat of RTV, which will discourage seizing but also help to slow or block any migration of coolant due to microscopic cracks or rust-through. Care should be taken not to apply the RTV to the bottom of the stud. The fine threads can get oil, or be torqued dry, it's been done both ways and it's worked fine both ways.

My personal opinion is that if you've got warpage in the head, you should have the head resurfaced. It's relatively cheap and it's not a big production to take it to a shop. I have heard that there's a right and a wrong way to secure the head in the mill, others may know more about that. A good shop can also mill the head with the correct RA value for surface roughness, which will help the gasket adhere properly.

The other reason to have the head milled is that you likely also have warpage somewhere on the deck, so putting two warped parts together increases the risk of leakage.
