i have a windsor block and im going to put some romeo heads. i've noticed that theres different part #s in the windsor timing chain kit and romeo timing chain kit. whats the difference between them, which one should i get? thanks in advance

 

If you are just swapping heads and nothing else, you will need a romeo timing cover as the Windsor heads have a larger bolt where the timing cover meets the heads....other than that, I am not sure that there is a difference between the timing chains themselves....I swapped from romeo heads to windsor heads and the only thing that was different was the cover as I said.
