Which head gasket bore for 408 build??
I知 building a 408 with a lq4 block and 821 heads. What head gasket bore would be the best to go with? I知 guessing bigger than 4.065 because of the size of the LS3 chambers? Should 4.08 work? I知 a noob when it comes to head gaskets for custom builds. 4.030 bore, but my heads are off of an engine with a 4.065 bore. Any help or recommendations appreciated, folks! Engine will be naturally aspirated and sprayed a moderate shot.
