I would like to know what your cranking compression is.
Lowering the LSA will increase the cranking the cranking compression of that engine, which may be beneficial to you in this case. You may want to go that route. Be mindful of overlap as well.
I can't find an off the shelf cam to recommend at this point.
I agree with Yellow Rose, call a cam grinder. Before you do, find out what the cranking compression is on your engine. That will prove useful. The static compression ratio isn't always the end all be all.
The more information you can provide to them the better.
