arp told absolutly not to do that, i talked to them last week

are you using their ultra torque lube?

yes sir, guys at the track told me this but i wanted to make sure before i go killing the studs

What are you using for head gaskets? You got any pics of the heads? I've seen a set of studded gaskets leak because the previous owner had a set of fire-rings installed and they where done very poorly.

There has been a real big debate on another forum about what value to torque these studs to. While they might not agree on what the value is, almost everyone agrees that the 210ft-lbs is in sufficient. IMO if you are going to exceed the 210, I wouldnt go more than 20% as that is probably a safe assumption that the margin of safety is no doubt more than that. That would put you at about 250ft-lbs. I would start there and see if it holds. JMO.

Who checked your heads and block when you had it apart?

[travlys]

machine shop checked heads and ford "checked" the block

checked or decked? difference between the 2!

arp said if you exceed the torque spec you will end up yeilding the stud and end up with bolts that are no better then the stock ones!

my bad, they were decked
