LT1 vs LT4 Head Gasket differences
The LT1 uses head gasket part number: 12659260 (old number: 12622331)
The LT4 uses head gasket part number: 12654622
The LT1 head gaskets are silver with red and the LT4 look to be silver with black. I know there is more to the LT4 other than the color difference. Does anyone know specifically what is different between them exactly? Thanks

I have them both here. I’ll lay them on top of each other and check the differences. I can’t imagine they are any different since the blocks for the LT1 and LT4 are the same, the gaskets would have to be the same as well.

Ant please check the thickness of them due to my motor build I may go with a set of the LT4 with this is the case... If you dont care give me a message on what you find out or see from the diff's. Robert
