I got ahold of a set of 1970 351 heads with a fresh valve job with 1.91, 1.61 valves, for free so i was wondering how they would work on my 5.0 with an e303 cam, bbk shortie headers, cobra intake, and 70mm throttlebody, or would i have problems

Not sure if it will work. I have a set of 69 high performance 390 heads, will these bolt up to a 5.0 w/B-cam, shorties 70mm throttle body, & cobra intake? These heads are just sitting on the shelf in Dad's garage. I was told I could have them, but need to know if they will work. Thanks in advance.

a 390 is an FE engine (different type block than 302) and im pretty sure they won't work.
