Default 2001 PT Cruiser Head

I have a 2001 engine in the machine shop for rebuild. Found out after inspection that the head is too warped to rebuild. Also hearing that the 1st year (2001) heads (4667086AB) were a bad design and the design was changed for 2002 and on.

Logic follows that it would be more desirable to procure the better head (4667086AC) design to rebuild rather than another 2001 (4667086AB) head.

Will the newer 2002, 2003 etc. head be a compatible swap? Or did they change other things as well, which you would also have to swap in like intake and exhaust manifolds etc. I see several 4667086AC heads out there. The AB heads (2001) and hard to find, at least a good one (one within specs).

Additionally: Are the cams the same between 2001 and 2002?

Haven't heard heads were bad or Had defects. Aluminum, no matter the maker, starts doing weird stuff at ~350f.

'02 & up heads were different in that they had the 'bulge' large hole' vs the 'Bulge' 'small hole' of the '01.
You would need to look at your block to see if the '02 & up would fit; right above starter is where the 'bulge' in question are, or aren't.

I DO have an '01 head I just cleaned. I need to put a precision head gauge on to verify straightness, but let me know if you're interested- I can provide pictures and spotless references.
