Crank and Cam Shaft Center Distance on an RB Block

[BLAM]

I am looking for the Stock RB Center Distance dimensions.  I am trying to determine if I need to buy an undersize timing chain setup?  My align honed block now as Center Distance measurement of 5.142" but I do not how the compares to a non-honed block and if I need an undersize chain.  The engine is a 4.25" stroke 3 bolt solid roller cam motor.

Thanks

Generally when you align hone a block you don't hardly move the centerline enough to even worry about the distance between the cam and crank but when you alignbore a block because of a serious problem such as a spun main or something else and you have to move the crank centerline up go get the main saddles to clean up thats when you might have to worry about the distance a little bit although I don't know what the options are for the timing chains.

I had the block align honed because I had new aluminum main caps installed.  I think the stock center distance is 5.146", but I need to confirm.  I called the Cloyes tech line, but the individual who would know the answers is out on business travel.
