The only problem you're going to run into is the lifters.... You will need to use conversion lifters, or have the lifter bores drilled out and press fitted with bronze bushings tall enought to accomodate the factory hr lifters. You will also have to drill an tap the holes for the spider hold doen bolts in the lifter valley.

Check out the aftermarket, too. I think comp cams sells a drop-in kit to convert a non-roller block to roller lifters. I'm pretty sure it's easier than retrofitting the OEM setup.
