I have BAM .210-offset intake lifters in my RB block w/ Victor heads. With a .600"-offset intake rocker, no problems. When I mocked up some T&Ds .725"-offset MW Victor intakes, some of the intake pushrods rubbed against the casting bosses the block has for the most inboard head bolts. Considering most Indy 440-1 intake rockers I've seen have a .800" offset, that would only make the clearance issue worse.

I suppose the alternatives are either grind additional clearance on those bosses (which I've seen done) or see if no-offset intake lifters move the pushrods far enough away from the block bosses to not have a problem. But then you have more severe pushrod angularity, which would be even more on a low-deck vs RB block. Everything's a trade-off.
