K I got a question. On a 383 BB can you swap the heads for 440 heads? And if so do you still run a 383bb intake or a 440bb intake? Got a blower setup complete with carbs scoop and everything for $1200bones and all I have runnin for the momment is 383. Thanks
All the heads will interchange, it is the deck height between the blocks, "B" for 383 400, "RB" raised block for the 440 stuff.
You will have to run the 383 intake on the 383.
