When calling around for a new head I've been asked about whether it's a straight or slant cam. I don't know what this means. Any idea. And where can I find the casting number on the head? 1997 Saturn SC2 1.9L DOHC

The SL is the small 4 door
The SC is the 2 door Sport Coupe
The numbers refer to the engine. The all have a 1.9 liter. "1" is a Single Over Head Cam, 8th VIN will be an "8". "2" is the Dual Over Head Cam, 8th VIN will be a "7"
So a Saturn SL2 with be a 4 door with a DOHC 1.9 liter. SL1 will be a 4 door with a SOHC 1.9 liter. SC2 will be a 2 door with a 1.9 liter DOHC. SC1 will be a 2 door with a 1.9 liter SOHC.
1.9L SOHC - head gasket set which includes all gaskets needed to remove cylinder head with thermostat runs about $150.00. Head mechine ( check for cracks and milled ) $145.00. Labor time to remove and reinstall cylinder head 8.5 hrs X shops labor rate.
1.9L DOHC - head gasket set and thermostat runs about $210.00. Head mechine $175.00. Labor to remove and reinstall cylinder head 10.7 hrs X shop labor rate.
Labor times per Mitchell labor book, this is a guide all repair shops used.
I had the same problem with a 97 sc2. The fix for my car was the temp sensor that controls the extra fuel when engine is cold it didn't sense that the engine was warmed up and added extra fuel flooding the engine.
