Will an LS1 head off a 99 Trans Am fit and work on a 98 Corvette? I got a good deal on a set to have ported to put on my 98 Vet, but before I get the port work done, I want to make sure they are exact replacements. Any help would be appreciated.
Re: Corvette LS1 heads vs 99 Trans Am LS1 heads? (VettesandZs)
i don't know,but I would look on the heads and see if they have the same part number.That way you know you have the same heads,or maybe a telephone call to the Cevrolet Parts counter.I am sure they could help you also. :chevy :chevy :flag :chevy :chevy

yes, they will work. Be sure to get the same model year head gasket, especially if the heads are 853 castings with the dimple in the deck face at the #6/#3 cyl position. If you have these heads you will need the composite head gasket p/n# 12498543. If you use later model mls gaskets with these heads, you may develop a coolant leak.
