Default Compression ratio help
I’m starting my 390 build and have a question that I should have gotten answered before now.

What do I need to do to get to 10:1 compression with this combo. I thought I would be fine but the more I read the more I think I’m going to come up short. This is my first FE and first build and I guess I’m just getting nervous. I’m also wondering what head gasket to use.
