320 head has bigger valves

That the 320 head will bolt up but you may have piston clearance issues. Also you'll need to deal with the injector holes. Regardless, you'll need to use the cam out of your '02 head because the 320 dizzy spins in the opposite direction.

If you have smoke on deceleration you need valve guides and seals. My advise would be to get the original head referbished with new guides, seals, rockers, springs and seats reground.


Here's a picture of my cylinder head in the process of having the exact repairs list above completed.
