Greetings . . .

Perhaps I misspoke on this thread in that although the blocks are essentially the same there is additional machining to drill holes from the oil gallery into the lifter bores when hydraulic lifters are to be fitted. Whereas solids are lubricated by oil draining from the top end.

So it isn't a simple swap of cam/lifter/push-rods . . . some machining would be necessary.
