not sure which gaskets to get for my LQ4 block with 243 heads?

GM LS2/L92/LS3/L99 Cylinder Head Gasket | Gaskets/Kits/Accessories | Engine | 98-02 Camaro/Firebird | WS6store.com

GM 6.0L Multi-Layer Steel LS1 Cylinder Head Gasket (Pair | WS6store.com

 

call the fellas at Texas Speed....most likely option two

 

Since the cylinder bore is greater than the head bore, get the head gasket to match the cylinder bore..
