Indy head install - torque spec / sequence?

[BS CUDA]

 Anybody have the suggested torque sequence / torque specs for installing a set of Indy heads?

As I recall if you use high end new bolts like ARP the torque spec is 10 lbs lower then iron heads so 65 lbs , I always torque in 4 steps so 45 , 55 , 65 , 65 again , the pattern is start in the middle & work in a circle to the ends .
 I use lube supplied with the bolts on the threads to make sure they turn smoothly , run a tap in the threads if you have one handy , before installing the heads.
 I hope you have a good MLS gasket such as Cometic , the Fel Pro will fail if they are not MLS as alum expands at 2x the rate of iron & it will fail the regular gaskets , it is just a matter of time !

Thanks CP - I also found the info a moment ago in my Mopar Performance Parts Big Block "B-RB" Engine book. With the internet so available I sometimes forget the print that I have available at my finger tips.

I will verify the gaskets as they are Indy supplied with the whole package - hopefully they would supply the quality stuff. Tap - yes, step torque - absolutely and yes the bolts are new as well.

Have fun with the swap . If I was closer I would come & help
