    You need to run whatever offset is necessary for those heads in order for the pushrods to clear the heads, and correct the PR alignment as much as possible. The only one that is different is the SB2, you can run them with the stock lifter location and offset lifters or get a block with the SB2 lifter bore configuration. Also requires a different cam, yours will not.
