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..... Will a 3800 motor and tranny fit into my LS 3400 CAR....I Would love to be driving a 3800 again...even my radiator support rotted away and I had to have L channel aluminum welded to myn frame to support my radiator and Oh my $120 shifting cable I fixed with gorilla glue $8 yep don't let me miss the $120+ power steering return line form fitted parts store order only ofcourse ....it's sad cause I've always been a bowtie guy and this one was a nightmare
