Head inchangeability

So, I have a 1976 280z. It currently has p90 heads on it. That's how I bought it. I know that the P79 as well as the p90a head will also bolt on.

My question is this: Do I need to get any specific gasket here or there for a P79 or P90a head? Or can I use what ever Felpro gives me for a stock 280z replacement?

I will be using the stock intake and exhaust from my 280z, just changing the head.

Welcome to ZDriver!
