you might want to test fit the hood.
When i dropped my motor in, i was sure that my hood would hit. But it fits great and with room to spare.
Besides, if it does hit you will know for sure what you need. And is only a few bolts, and a minute worth of time to just try it.
And get some pics so we can see it.
