Does the amount of tq you apply to the streach bolts change if you are using a graphite gasket or MLS gaskets?

I was also considering Head studs, how hard are those to install?

thanks

Far as I know the procedure for torquing head bolts does not change with different gaskets, and head studs are sweet, I plan to get a set next time I pull my heads.

 

Gaskets do not affect the torque. And yes, studs are the way to go. Studs are really easy to install. They also help when pulling the heads off next time: less time involved since no coolant will get in the block holes and you don't have to clean out the holes either.

 

I would also suggest if you don't do the studs at least do the ARP bolts.
with the ARP bolts and ARP assy lube, you don't have to tq the heads down as much to get the same seal.

 

How much are head studs and what is involved when installing them?

 

ARP studs are a bit over $200. That's why I went with new OEM bolts. The ARP studs/bolts are way easier to install though.

 

Studs are ~$250. Once you clean the holes in the block, *lightly* coat the coarse threads with some oil and thread them into the block by hand. Once the head is on...put the washers and nuts on with some moly lube. Torque them in sequence.

 

Spend the money on the head studs. They are well worth it.

 

Unless you plan on switching heads frequently or are going to have really high cylinder pressure, I'd just use the OEM bolts. $250 for studs that you're never going to see the benefit of is just a waste. Also, if you have the 845 heads, you cannot use the MLS gaskets, or they will leak coolant.

 

What are 845 casting heads?? I plan on using PP Stg 2 5.3L and I may do a few future head swaps so the studs will probably be worth it.

Guys, Do Not Use Felpro Head Gaskets And Arp Head Bolts IN A COMBINATION!!! Went Through 3 Gaskets.... The Specs Are Not Correct...went With The Studs And Graphite.....

 

What Fel-pro head gaskets did you use? I used 1041's and haven't had a problem yet, that I know of anyway?
