I have a 2003 mustang gt. Is there a difference between Romeo and Windsor heads.. Will my VIN tell me? Also if I have a windsor block, do they sell aluminum heads for it?

from what i read, the heads are mostly interchangable, found this thread:

and on page 2, it says what you have to do - post is by smitty77

they have windsor and romeo packages on thier website:

give patriot a call, and verify everything.

All modular heads are aluminum... You should have a romeo block and heads since your car is an 03, unless someone has messed with the motor in your car. The heads are interchangeable anyway, just need a few different bolts on the timing cover, and of course valve covers with the right bolt pattern. 11bolt romeo, 13/14bolt windsor, again you should have romeo heads and block.
