Does anyone know if the 95 MC Maristar LT1 motor has 4 bolt heads or 6 bolt heads?

My valves are bad and I have a friend with a set of rebuit heads off a 92 or 91 Firebird. They are 6 bolt heads and says the newer LT1 is a Vortec 4 bolt head...

All this is what he told me to ask, I can show you were the heads are but not what kind they are..( I know I can go look but the boat is in the shop and I am trying to get it running tomorrow..

Will the Firebird heads work in the MC ??

thanks..

92 heads (from a stock 92 firebird ) are not LT1 style heads. The LT1 came out in 93 for F-body cars or in 92 for the vettes which both featured reverse cooling.
