    I seem to recall not being able to use the MLS head gaskets on 98 heads. Could be wrong though.
    Part number for the MLS gaskets is 12498544 Bolts are # 12498545

    Thanks for the reply, but my car is a 98 and the engine is a 99 and also, that part# is for 02-04 LS1.

    Didn't know you had a 99 engine in your's
    02 is the earliest i've ever seen MLS gaskets stock. They should work on anyother year after 98 though
