hello everyone, this is my first post on this board!
im working on a 65 mustang, i dont know much of the history or about the engine.
it said 400 on the valve cover but i found rebuilt heads and intake for a 351c
should i put the 351c heads and intake on and set the heads that were on the engine aside?
cam shaft says "erson tq20h" will this camshaft have a nice lope?
pics of the heads for reference, the top heads were on the engine and the bottom heads were rebuilt and had a matching 351c intake
any advice would be greatly appreciated
