Need Advice On Magnum Crate Engine

Appears to be a smokin' deal. If it was me i'd slap it together and run it. Maybe. LOL
The heads appeared to have been worked. Maybe disassemble them and do an inspection. And a little porting. Or since you saved a bunch of cash, aluminum heads?
To be safe you probably should take it to a machine shop . I'm confusing myself. Haha
Opinions will vary.
