Head gasket recommendations for magnum

I can't believe you are anywhere near close on valve clearance with that cam. Even without reliefs.

Do the clay method and check it with the springs you run in place.

Edit: if you do need the .050 gasket there is a Fel Pro gasket that will be just fine. I can't remember the part number but someone here will have it for you.

Also, you need to figure out why the head gasket failed. You are detonating it, the surface finish wasn't correct or something.

Ill do the clay method and check it out. I think I was just cautious about the piston to valve clearence at the time since I’ve read about other builds being close with flat top pistons. I remember it did detonated a couple times when I really got on it but let off quickly. Maybe it took a toll on it. Also I figure since the previous head gasket was .050 compressed I get somewhat of the same but will check the clearence tho
