When installing head studs in the block how tight do you put the studs in the block. I am not talking about torquing the heads, just the stud in the block. Thanks Bill

Just put some sealant on them and snug them up, 10/15 lbs if your torquing. Make sure you remove the first thread use a counter bore in a drill.

Remove first thread on what Ron??

Ron is talking about a chamfer at the block face. I use only a 1/32"

The stock Ford studs do get minor tightening into the block, as suggested by Ron. However, non-Ford style studs should only be finger tight.

What happens if you don't chamfer the face?

Part of the thread can be "pulled-up" above the block surface by the stud. DD

Hey Bill,
I've always been told that not all head studs are open to water jackets. And, that some ARE open , because too much force/torque was applied to the studs upon installation...thereby forcing crack/opening when bottoming. Anyway, the point is, if your block threads/stud holes are properly cleaned ...just hand thread the studs , with lube, till bottoming (I use neverseize to prevent galling/seizing/rusting..chose your own poison).
The object is to get full benefit of all block thread strength. The 'torqueing/clamping' FORCE is applied to the nut...not the stud..IMO.

There are 3 blind holes in the deck. One in the middle and one on each end. These are over the exhaust ports. I forget how many threads are on a stock Ford stud but you only have to have 7-8 threads to take full benefit of a 7/16 stud or bolt. I know of no after market studs that meet these specs. In JWL's book he explains in detail the quality of the deck surface and why proper torquing is so important.
