Yes it is interchangeable, The Monte SS is different from the other models tho, LS, LS Sport, LS Competition so the LS models are interchangeable.

Thanks so much

Can I replace a 2003 monte carlo head gasket with a 2001 matte carlo head gasket??

Your talking a new gasket I hope, and I don't know off the top of my head if there the same, check with a parts store.

How about why my 02 LS 3400(POS) has now blown 3 head gaskets in less than 2 years and the last 2 didn't even make it 20,000 miles.....
