I think I am 100% certain that all the LTx heads will bolt up on any LTx engine

No bolt up issues at all. The later heads flow a tad better but they are all interchangeable.

i think 97 heads are the best flowing heads.

some castings are a bit thinner than others...i was always told that the 97's were a little oon the thin side, but they do flow. Hell im running 97's...

'92-'95 have more material to remove for better cfm when ported(easier to cover up small mistakes when porting)can do a race portjob.
'96/'97 are the thinner walled and will not flow quite as much due to lack of material but are still good heads its doubtful you will notice a real difference when a street/strip portjob is done to either head.they all still weigh the same 48lbs per pair assembled
