Head Gasket Suggestions

I have a 1984 Model 318 in my '69 Dart.

I have Hooker longtubes, Edelbrock Performer intake, and recently put in the Comp XE268 cam. I picked up a set of "302" heads from a pull-a-part for $60 and intend to get em to the machine shop for a freshening up with my new components that come in the cam kit. Aiming to just get them surfaced so no major milling. I am aiming for anywhere from 9.2 to 9.5-1 compression.

What thickness head gasket should i aim for? What are some good wallet-friendly solutions?

*I am also open to good header gasket suggestions*

I know I seen the post on fb but cant remember now but what are you doing with the bottom end? I went thru just about every scenero planning a 318 build I can help you out lol. What did you decide to do with your valve springs ? I remember you asking about the stock ones with that cam I suggested you not use them lol
