Ernie,
I really like the original equipment look and feel the engine has now. Well, you have it as it is blown up just like the originals did.
Not sure what the head numbers were but the 427 tunnel port that I had in 65 had aluminum heads and intake. And just like the original stuff it blew up. Only thing that I salvaged was the intake and two carbs. Ruined the block, both heads and everything else. I always figured since the engine was built by a racing shop, the heads weren't Ford heads but don't really know.
