Sources: Large Port Commando Heads

thats a standard comando head, the largeport needs ofset intake rockers and play in a diferent leauge compared to the standard comando and the RHS heads
the largeport head is/was more like a W series head, and i think they have been replaced now by a diferent head wich is called the supercomando i think..
this all depends on how seious you want to go and what kind of money you may want to put into it
