I'm sorry, but you plan to crack a Steel sleeved block how? I haven't once heard of a block cracking issue. Many times have people pulled the threads out of their blocks torquing their heads on. ARP studs are shorter than stock bolts, there are long studs, but they still pull, the stock bolts are frankly better because they will give a bit more before failing.
There are no copper gaskets so you can't O-ring.
You can time-sert, or something similar, or you can just risk it.
And "from what I've heard...LOL." Don't assume knowledge of members.
