Performer RPM Magnum heads?

I like them gutted but I want to also have the easy button so mine has steel doors with wind up windows, steel fenders and a tied together frontend that can be removed with four bolts. Simple mild engine that will run 6.0’s for three days in a row and never need the hood off. Hatch on my fiberglass trunk so I Dont have to remove the trunk to add fuel. And a 60 amp single wire alternator that I only have to charge the battery once a month just for insurance.
